Prevent Duplicate Entrys In MySql?
Jul 20, 2011
Okay guys, this might be very simple, but i just cant find the answer.
What i want to do is prevent users from submiting entries that already exist in the database using php. code...
All want is to be sure that if the there is an existing row in name with an entry of 'asdf' (example) then it will echo something like name already exists, but if it doesnt i want it to echo okay. What happens is that it ALWAYS echos okay, in other words it always says there is no row named 'name' with the value of 'asdf'

I am trying to make some IE-only JScript work on Firefox and Safari.
Does anyone know of equivalent methods for these functions?
document.selection.createRange()

It is only necessary that any equivalent functions work on the lateset
versions of Firefox and Safari.

My text and what I have been researching on the internet has not been very helpful in determining the code that I need to prevent a user from entering his/her information more than once. Here is my current code
<!DOCTYPE HTML PUBLIC "-//W3C//DTD.HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/htm14/loose.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

I have created a new web page to link the duplicate cookie too, titled doubleinfo.html. This is what I am using to let the user know that their information has already been entered.
My text is telling me that I need to look for a nextform() function, but I didn't have to write one so what would I need to do, if anything, to start the document.cookie = "name" codes?

I have a single dimension array with the following data stored on it.
a[0] = 1~1~10
a[1] = 1~2~11
a[2] = 1~3~15
a[3] = 1~4~19
a[5] = 1~6~10
Here in my case a[0] and a[5] is duplicate because i am using 1 or 0 for active and deactivate purpose a[4] is deactivate value so we can ignore the 10 in this. so in my case 10 is repeated twice on a[0]and a[5] not a[4], so its duplicate value. can any one help me to solve this.

The problem I am having is when the following script is executed within my page and the user submits the form, the variables passed to the GET array are duplicated only for the inputs created by my script. I have other inputs in the form that are created within the HTML of the page that work fine (i.e. they only try to pass their value once) but I cannot get my script to work properly.
Here is my script:
Here is an example of what the url looks like after the form containing this script has been submitted:
The input (segments) created in my page only submits itself once, while anything created by the script (segment_type_1, segment_type_2, etc.) submits itself twice with the second, blank value overriding the first, correct value.

Based on the code above, i wanted to generate an array of input which have the ID "ordDate", so to populate the data into the input, i identify by name attribute.It works fine if i remove the ID for the input, but in my case,the ID is compulsory. Is there any workaround to cater for my needs?

I am having a table with rows created using a button click event. While adding rows to the table, I create drop dowlist using
Code:
objVehicles = document.createElement("<SELECT class='dropdownbox' id=Vehicles"+objAlertRowId+" name=Vehicles"+objAlertRowId+" STYLE='width:148px'; onchange='setDataChanged();toggleEditButton(" + objAlertRowId+ ",this.value);' >");
objNewRow.cells.item(3).appendChild(objVehicles);
And the output will be like the attached screen shot.
The control name as Vehicles0,Vehicles1 and so on Now I want to restrict that the the user select no duplicates from the List.
What logic I can implement ?

Problem: I have two dropdown list boxes with same data(all data driven).
These are used for two separate entries. For every entry you cannot choose the same value twice. For example, I cannot choose for entry 1 the same value in both selection boxes (gqCategory1Entry1 and gqCategory2Entry1)
This part works.
The second entry is the problem: When I choose a value for Entry
Two that is the same as in entry one it thinks that "Dubplicate
Divisons have been selected").
WHen in fact these are two separate entries.

What's supposed to happen is when the program is run the user clicks on "Select your Numbers!" their then asked for 5 numbers which they input and then the numbers are checked by a function called �isAlreadySelected� for duplicates and if there is an alert is shown. When 5 numbers are entered correctly then they are shown by a window.alert.
Its done in to 2 functions
When I run the below code I'm prompted for the 5 numbers but it isn't checking for duplicates and my selection is undefined.

I'm trying to duplicate some PHP code in JS, but keep running into "invalid quantifier" errors for regular expressions.Here's an example of what I'm working with:
Code JavaScript:
var elementId = 'ipaddress';
var regexsplice_IP_ADDRESS = '(?:[0-9]{1,3}.[0-9]{1,3}+.[0-9]{1,3}+.[0-9]{1,3}+)';
if(!RegExp(regexsplice_IP_ADDRESS).test(elementId.value))){
[code].....
1) do I need to double up on the backslashes within a string using single quotes on characters that are seen as escape characters in regex, but not javascript?
2) do I need to start and end the string with a special character, like I would with preg_match in PHP?
3) To use the RegExp() function to prepare a regular express created from a string...can I use it like in the example above? Or do I have to use a separate delcaration like: var theregex = new RexExp(regexsplice_IP_ADDRESS);

I am calling 2 scripts, that are variations of the same script, and am getting unwanted duplicate output into the other div (place-holder) on an html page. I thought it was a scope issue, but that doesn't seem to make sense. The page is: [URL]
features.js
$(document).ready(function() {
$.get('xml/features.xml', function(f) {
$('#y-place-holder').empty();
$('#y-place-holder').append('<dl class="feature" />');
$('feature', f).each(function() {
var $feature = $(this);
var fimageurl = $feature.attr('imageurl');
var fseries = $feature.attr("series");
var ftitle = $feature.attr("title");
var fdates1 = $feature.find('dates1').text();
var fdescription = $feature.find('description').text();
var ffeature = '';
ffeature = '<dd>'; .....

With my very limited knowledge of both jQuery and JS i made a small script (with a little help) that duplicates a tablerow when a button is clicked. This works like a charm, however, i would like to add a datepicker to it. This also works well, but just once and not on the copied fields or visa versa. It's probably because the datepicker "thinks" there is just one field.I found several sources to solve the problem, but again, with my newbie knowledge, it's just to hard. I am playing with this for almost two days and can't get it solved.
<script type='text/javascript'>//<![CDATA[
$(window).load(function(){
$("input[type='button'].AddRow").click(
