Convert Php Array To Array And Populate Form Text Fields
Nov 3, 2010I am working on a page where the user will select a location from a dynamically generated dropdown list. I was able to create the php multidimensional array (tested and working) from a MySql database using the users information at login, but I'm having problems converting it to a javascript multidimensional array. I need to be able to access variables that I can pass to a number of text fields within an html form.For instance, if a user belongs to a company with multiple addresses, I need to be able to let them select the address they need to prepopulate specific text fields.

Sep 22, 2010I am creating an array based on form elements. I then am trying to create an IF (and nested IF) statement to check if the fields are empty and then with the nested IF statement use certain fields to create mathematical functions.
So far I have this:
function QuantityMWh(form) {
var formchk = document.forms[0]
for (i = 0; i < formchk.elements.length; i++) {
if (formchk.elements[1].value == "" && formchk.elements[2].value == "") {
[Code]....
It's only checking the first field and not the second, and vice versa. i.e. if only one field has text then it passes.
Input #'s Into An Array Using A Form?
Nov 10, 2011Lets say I have an empty array and I want the user to be able to enter as many new numbers as the user wants into the array. Could you explain how? Simply put it: How can javascript parse a textarea and input it into an array. (Like if the user entered 1 3 5 7 4).
<script>
function example(form){
var myNumbers=new Array();
then I'll do something with the array once the #'s are loaded...

Using An Array Repeatedly In Form?
Dec 14, 2010I am new to JavaScript and self taught, so please bear with any terminology I use incorrectly. I have an array defined. I am trying to access this array multiple times (10) in the HTML. It worked on the first drop down, but when I added the next one it errored. Not sure if what I am trying to do is possible or if I am going about this the right way. Below is the code:
Code:
var Engagements = [];
Engagements[0] = new Option("","");
Engagements[1] = new Option("Asset Management","Asset Management");
Engagements[2] = new Option("Autoclave","Autoclave");

Get Value From Array Element Of A Form ?
Sep 22, 2011Having a form like this:
HTML Code:
when I capture the dispatch of the form and try to get the value of any of these file fields:
PHP Code:
There's a Javascript error saying that form.file is undefined. It's strange because I see in Firebug that "file" actually exists as a property of "form". The same happens if I get rid of the temporary variable "form" and I do it this way:
So, I eventually had to use the getElementById('image' + i) method in order to do what I wanted. But there must be a "natural" way to get a value from an array defined in a form.

Set Value Of Array Of Form Elements
Oct 14, 2009I have a form that has an array of input values:
I do this so I can loop through the values in php... now...that's the easy part... the hard part comes to this:
Next to each of those boxes is a search button that allows the user to open up a popup window that they can search for an item, and select the item. Once they select the item it should populate that particular input box with the selected item. I can easily do this with a uniquely named input box, but can't seem to figure out how to do it with an array of input boxes...
Form Elements Array Not Being Updated
Oct 28, 2009I use a very handy function (onsubmit) to validate empty fields in a form:
PHP Code:
function validate_form(){
var x = document.getElementById("form1");
for(var i=0; i<x.length; i++){
if((x.elements[i].value == "") && (x.elements[i].title)){
[Code]....
It worked like a charm, until I had to change a dropdown dynamically with ajax. I have two dropdowns, the second being populated with ajax (php, mysql) by the option selected in the first one. The second dropdown has the title attribute filled so the previous function can validate and ask the user to select something. However, it seems like fields loaded dynamically with ajax wont appear inside the x.elements[] array. I've tested it over and over, it keeps ignoring it. It isn't even in the array. Why?
Getting A Collection Of Form Values Into Array
Nov 11, 2011'm having a very hard time making this work and be happy in both IE and Firefox. Basically, I'm setting a timeout to get an array of the form values if not present, or compare against if they are present, and if any change in values, submit the form to auto-save it.
below is my coding, basically I am using document.forms[thisformname].elements - but that gives me a lot of things that are NOT form fields and I just need to read input:text, input:checkboxk, input:radio, textarea, and select elements - nothing more. I'm open to any suggestions and some of you smart guys could probably write this in half the lines I did.
Code:
//auto-save coding
var autosaveTimelapse=0;
var autosaveTimeout=3; //every n seconds

Form Validation -> Checkbox Array
Sep 19, 2006<form name="new_page" action="test.php"><input type="checkbox" name="allowed[]" value="2">
<input type="checkbox" name="allowed[]" value="2">
<input type="checkbox" name="allowed[]" value="2">
<input class="button_140" type="button" value="Toevoegen"
if (!document.new_page.allowed[].checked){ popupalert('allowed'); }
else { this.form.submit(); }"></form>
This is a piece of the code I've written. It's supposed to check if one of the allowed[]-checkboxes is checked, and if not, to run function popupalert('allowed');. It's not working. Can someone tell me how to fix this?
Using Option.length With Php Array In Form
Feb 16, 2009Ok the setup is basically this. The user selects a option in a drop down field, whatever they select through javscript additional records are populated in a second select field. This second select field allows for multiple selections, however I am submitting the form to a php script and I want to capture the multiple selections in the second select field. To do that for php I need to turn the field into an array so I have to add the brackets, [], to the name of the select field.
In php you can name the field like so:
Code:
<select name="fld[]" size="1">
The problem is in the js function when I give it a field name with [] the script doesnt work. Here is the js function:
Code:
function channelform(select_value) {
IntPath = document.channel_form.cid[]
TheOptions = IntPath.options.length
[Code]..
You can see the [] for the cid field name. Whenever I add that to the field name the js script is broken. How do I get it to work so that I can pass an array to php when the form submits?
Form Input Array Validation
Mar 6, 2004The form contains 3 file input tags. The name for each is an array. This is for further processing by PHP script. I want to make sure at least one of the file input tags has selected a file.
The rest of the validation script works, but I get a 'not object' error when I include the section that checks the file input tags. Code:
Form Array Checkbox Accesing
Feb 21, 2005First I'm sure the answer to ths JS question is buried somewhere in the many item of this forum. Just could not find it. So I'm working on changes to a form developed by someone else. In the form the previous developer wrote the following:
<input type="checkbox" name="method[]" value="payroll_onetime">Payroll
<input type="checkbox" name="method[]" value="payroll_onetime">One-time
<input type="checkbox" name="method[]" value="paper">Paper Check
<input type="checkbox" name="method[]" "onlinebill">Online Bill
Note there are other form and HTML I removed.
So my problem is this. I'm trying to access the method checkbox array from a JS function. So I write:
function setPayrollStatus()
{
alert(document.profile.method.length);
}
This does give me that value of 4. Since there are 4 checkboxes for method I'm thinking this is correct. So next I add:
for (var idx=0; idx < document.profile.method.length; idx++)
{
alert(document.profile.method[idx].checked);
}
Now I get only 'undefined'.
What I want to accomplish is to check the first item. I thought I would be able to write something like: document.profile. method[0].checked = true;
If I change the form name tags from 'method[]' to 'method' it works. Problem is he also wrote the php back end processing for this form. And in PHP this syntax yeilds an array for the method vriable.
Referencing Array-syntax-like Form Variable
Mar 26, 2007I am experience some problems reading a form variable from a
Javascript function. The point with this particular variable is that
its name has the following syntax:
<input name="tx_impexp[tt_content:159]"/>
I want to set this var to 1 from my javascript function, so I tried
to execute the following line of code:
document.frm_1.tx_impexp[exclude][tt_content:159].value=1;
Unfortunately the following error come up:
Error: missing ] in index expression
document.frm_1.tx_impexp[exclude][tt_content:159].value=1
--------------------------------------------------------------|
It seems Javascript expects to close down the bracket at the position
marked...An easy solution would be to change my var syntax but the
point is that I cannot since I am using an already made script and I
should not modify it.
Just wandering if this is due to a syntax error defined according to
Javascript specification language or there is something wrong with
this.

Form Validation For Checkbox Named As Array
Jul 24, 2005I have a number of checkboxes and radio buttons in an HTML form that are named as arrays, ie.
<INPUT type="checkbox" ID="i1" VALUE="MILK" NAME="Q1[]">
<INPUT type="checkbox" ID="i2" VALUE="SUGAR" NAME="Q1[]">
<INPUT type="checkbox" ID="i3" VALUE="BISCUIT" NAME="Q1[]">
I need to keep the 'NAME' as an array as above because of the form processing that is used after submit.
I was really hoping to use Javascript to validate the form and make sure that each checkbox group has at least one option selected , but my javascript messes up because the 'NAME' is Q1[] as opposed to Q1. I had been using:
<script>
function validate() {
if (!(mainform.Q1[0].checked || mainform.Q1[1].checked|| mainform.Q1[2].checked)) {
alert('Please answer question 1.');
event.returnValue=false;
}}
</script>
but this only works when I name the checkboxes NAME="Q1". Is anyone aware of how to get the validate function to work (or another way of validating the form) even when the checkboxes and radio buttons are named like NAME="Q1[]".
Check If Form Field Exists And If It's An Array
Sep 5, 2007I want to validate a form. In the form is a text field named 'extra[]' where the user inputs a number. The number is what I want to validate.
However, the 'extra[]' field is dynamic and does not always appear in the form.
If it appears, there may be only 1 occurrence of it which means it's then not an array but there may also be multiple occurrences of it.
I have a script that validates (and work as it should) if the 'extra[]' field occurs multiple times and is thereby an array, but I can't figure out how to validate the 'extra[]' if there is only 1 and to not throw an error if it's not there at all. Code:

Using Hidden Form Field In Array For Validation
Mar 29, 2011I have an order form where a customer can select a number of artwork prints supplied by different artists and suppliers. The name, price, postage amount and other details for each of the prints are held in a table in a MySQL database. As postage amount may vary between prints and suppliers of the prints we must have the customer select postage per print - not the amount just yes or no. The customer may select as many of these prints as he desires - printa, printb, printc, printd etc. through to printz. Many of the prints are provided by separate individual suppliers and must therefore have postage paid for each ordered print and this is automatically added by the order form. However some prints are provided by the same supplier and only one postage fee needs to be chosen (yes or no), so these are not automatically added and the customer must choose to pay postage on only one of the prints (not all 3 if he orders 3 of them).
So for postage purposes I have a postage code on the table in the MySQL database. For example printa, printb and printc are all supplied by the same supplier so each have a linked postage code of A. Similarly others may also be linked using different postage codes e.g. printx and printy may have a postage code of B. So whenever a customer chooses a print that does not have a linked postage code then the postage fee is automatically selected for him and charged to the total. However where prints are linked to the same postage code we must allow the costomer to select postage (yes or no), but we must force him to select yes or no for at least one of the linked prints.
So to do this I need a javascript validation alert to force the customer to choose yes for postage for at least one of the prints, not necessarily all of them, where they have a linked postage code. To do that I can add the the postage linked code as an array for each print selected to a form hidden field so that my javascript can use the field as follows: <input type="hidden" name="postagearray[]" value="<? echo $postagecode; ?>">

JQuery :: Accessing Form Inputs When Part Of An Array?
Dec 28, 2009im pretty new to jQuery, but familiar with JS in general. im trying to get a dom element by id to change the read only attribute. using jQuery i'm doing the following: var field = $('#name[index][index]').
but when alerting the field value, i get [object Object] and not an inputObject as i would expect.
i can use the normal getElementById and it works as I would expect. Is this a problem with jQuery?
