I'm trying to do a basic set of functions that will copy values from one multiple select to another multiple select. Here is the Javascript:
And here's some sample HTML:
The problem is that, when the PHP file does a count() of $_POST['addOwners'], it returns 0 if I add or remove any users. Any idea why?
Code:
function addOwners(addSelect, delSelect) {
var add = document.getElementById(addSelect);
var del = document.getElementById(delSelect);
// Get the names in the "users to be added" selection and the current owners select
var addOwners = add.options;
var curOwners = del.options;
// If a user is selected, add that user to the current owners list
var i = 0;
for (i = 0; i < addOwners.length; i++) {
// If the object exists
if (addOwners) {
if(addOwners.selected) {
var index = curOwners.length;
curOwners[index] = new Option(addOwners.text, addOwners.value, false);
// Remove the reference to this object
addOwners = null;
// We set i to be -1 so that the for loop will increment it to 0 and
// re-iterate through the list
i = -1;
}
}
}
}And here's some sample HTML:
Code:
<table style="width: 100%">
<tr>
<td style="width: 40%; text-align: right">
<select name="delOwners[ ]" id="selectNonowners" style="height: 7em;" MULTIPLE>
<option value="2">afrotiff</option>
<option value="1">jrh3k5</option>
<option value="7">mkb</option>
<option value="6">Omega6744</option>
<option value="4">tnb324</option>
<option value="3">TootSweetie85</option>
</select>
</td>
<td style="width: 20%; text-align: center">
<span class="smalltext">
<input type="button" onClick="javascript:addOwners('selectNonowners', 'selectOwners')" value="Add >>" />
<p />
<input type="button" onClick="javascript:delOwners('selectNonowners', 'selectOwners')" value="<< Remove" />
</span>
</td>
<td style="width: 40%; text-align: left">
<select name="addOwners[ ]" id="selectOwners" style="height: 7em;" MULTIPLE>
</select>
</td>
</tr>
