Summing Variables
Dec 11, 2001
I just have some fields for people to enter the number of tickets they want in four categories. This number of tickets in each category (member, nonmember, etc.) is multiplied by the ticket cost, which is being pulled out of a database, and then the total of the four categories is meant to be added up.
I have checked that the database values are correct and they are displaying. In fact, the script works fine when it operates just on any one input field - multiplies correctly and returns the right result.
The problem seems to come up whe I try to add the four input box totals after multiplying them by the ticket price. It gives me 'NaN' in the output field. Here's the script i'm using: Code:

I have a form that I am trying to loop through the elements of and come up with a total, when the form is submitted. The goal is to alert users that they have not entered a minimum or maximum number of choices before letting the form submit. The fields in question might be checkboxes in some cases (with a value of 1) or textboxes in others with user-submitted values. Here is a stripped down example...The html
<form class="phpws-form" id="elections_vote" action="index.php" method="post">
...
<input type="text" name="Candidate_Vote[2]" id="Candidate_Vote[2]" size="3" value="" />
<input type="text" name="Candidate_Vote[3]" id="Candidate_Vote[3]" size="3" value="" />[code]....
...problem is, is that total is always 0. I know I'm missing something, and I suspect that 'inputs' is not what I want it to be,

I have a Javascript array object like this:
[0][0] - 32[1] - 13[2] - 26[1][0] - 8[1] - 17[2] - 4[2][0] - 10[1] - 30[2] - 22...etc
and what I want to end up is with an array with the sum of the [0], [1] and [2] values, so for instance with this example, I want an array returned like this:
[50, 60, 52] i.e. this is [(32+8+10), (13+17+30), (26+4+22)]
My real problem with this is that the "inner array" can be any number of (its dynamic), so in my example its just 3 values but it could be for example 5 values e.g.:
[0][0] - 32[1] - 13[2] - 26[3] - 16[4] - 6etc

I have a program written in Javascript and fully functioning which takes a user-selected directory name and then displays all the photos in that directory in a certain format.
I am now wanting to expand the program to allow users to optionally enter their own strings and the program will use all the photos from www.flickr.com which use that string as a tag.
I have a PHP interface to flickr (called PHPflickr) which collects all the relevant photo urls. I now need to get these images back into my Javascript so I can process them using the existing functions (rather than rewrite all my functions in PHP code and have two sets of functions in the program). I found on another thread a means to do this for a date variable:
var jsArray = new Array(
<?php
$length = count($monthDataArray);
for ($i = 0; $i < $length; $i++)
{
echo '"' . addslashes($monthDataArray[$i]) . '"' . (($i < $length - 1) ? ',' : '') . "
";
}
?>
but being completely new to PHP I'm not sure what "addslashes" might be or what formatting will be necessary if I am starting with an array of urls. Code:

I thought it was possible to send two variables in an URL like this:
print" <script type='text/javascript'>
document.location.replace('http://127.0.0.1/add_task.php?tk_request_name={$req_name}?tk_req_id ={$maxValue}');
</script>";
but I can't get them separately in add_task.php
is there something wrong with script?
I use this code in some other PHP code.

Lets say I have a variable declared as such:
var newVariable="opener";
How can I then use this variable to access the opener of 'window' ?
Meaning, I dont want to access it as such:
window.opener
but as: window.+newVariable
So it uses the contents of newVariable to access the opener.
I need this because I have a couple of variables which I need to concat to eachother as a string,
and this string in turn is the variable I need to access from window.opener.varSomething
where varSomething is the variable that stores the variable I need to access.

Not sure if php is the best solution or maybe javascript. ( or both.)
I am writing a litle script that will go to my mysql table and take out 20 rows ( from about 10,000 rows ) based on the WHERE statement.
Then I want to step through these 20 rows displaying just two filds in this fashion:
First, I want to display one field in a "box" ( using divs and css ) then wait for a form input. Then while keeping the first displayed box and field display the second field in a similar box a fee lines below. Wait for a form input update some data.
Then onto the next row.
If I use javascript then I could keep all the processing on one page and not have
to have server refreshes.
But how do I get these those array elements from $row['field1'] and $row['field2'] into javascript vars ?
Is this the best way to do this ?
Or would php and having a couple of extra trips to the server for form processing be better ?

I need to create a variable out of nothing. From a database I extract an
item with a certain id. With this id I want to create a new variable.
For example:
id = 36;
"item"+id = new Array();
Now I get the message "Illegal left hand assignment".
I tried:
eval("item"+id) = new Array();
Is it possible to create a variable out of nothing?

Looking for clarification of undefined variables vs. error in
JavaScript code.
e.g.
<script>
alert( z ); // this will be an error, i.e. an exception
</script>
<script>
alert( this.z );
alert( window.z ); // both equivalent, no error, but window.z is
'undefined'
</script>
why is it that 'z' alone without the global object generates an error,
shouldn't it also be undefined? for example if i did
z = 0;
the javascript interpreter knows to create a global variable z

how you would piece
together a variable name and then assign it a value. I want to create a
hidden field and assign it a value based on the value of another variable
Right now it looks like:
("document.all.SM_MARK_10" + dateNumber + ".value")
where dateNumber is an already defined integer. What I want is to say
document.all.SM_MARK_1001.value="XX"
document.all.SM_MARK_1002.value="X2"
etc.
based on that value of dateNumber. Any way to do this easily?

Is there a way in Javascript to store a value to different variables in 1 command, something like code...
What I try to do is avoid errors by typing the value only once in code. I could do the following, but thought there might be a more direct way code...

url example:
whatever.com/index.html?name=username&password=password&gender=male&age=18
function getE(){
var url_string = String(document.location);
var url_array1 = url_string.split('?');
if(url_array1[1]){
var e_array = url_array1[1].split('&');
for(i=0;i<=20;i++){
if(e_array[i]){
pullE(e_array[i]);
}
}
}
}
function pullE(val){
var useVal = val.split('=');
alert(useVal[0]+" == "+useVal[1]); //display purposes
}
this would alert in order:
name == username
password == password
gender == male
age == 18
where useVal[0] is the element name and useVal[1] is the value.

I was wondering if someone would be so kind as to help me out in understanding a few things about sending a variable through a URL..
firstly:
i have two pages on page1.html i have a link which is:
window.location = "page2.html?name=yournamehere";
on page2.html how how would i be able to access the variable "name" ?
i know the following code works for strings, but i want to be able to directly access the variable that has already been assigned a value.
function parse(){
var Loc=this.location.toString();
var URLarray1=Loc.split('?')[1];
}
