checkbox help *solved*

Recommended Posts

hey guys,

I have a form that has multiple checkboxes, I want to be able to retrieve the value of the ones that are checked but for some reason this isn't working and I can't seem to find out why

$aBottles = array();
$aQty = array();
//$_SESSION['reserve_qBottlesCount'] returns 1 like it's supposed to
for ($i=1; $i <= $_SESSION['reserve_qBottlesCount']; $i++) {

and this is part of the form

<td> <input type="checkbox" id="chk'.$c.'"  value="'.$bottles_row2['name'].'" style="height:17px; font-family:tahoma; font-size:10px; color:#9A400C "/> </td>
<td> <strong>'.$bottles_row2['name'].'</strong> </td>
<td> Price: $<span id="txtPrice'.$c.'">'.$bottles_row['price'].'</span> </td>
<td> Qty: <select id="sel'.$c.'"  style="width:40px; height:17px; font-family:tahoma; font-size:10px; color:#9A400C ">
<option value="val0">0</option>
<option value="val1">1</option>
<option value="val2">2</option>
<option value="val3">3</option>
</select> </td>

everything is displayed the way it's supposed to and if I look at the source of the page I can see that the id of the checkbox is chk1 like it's supposed to be..

any clues why it's not working?


when I echo $_POST['chk'.$i] it doesn't output anything, even though there is a value and the checkbox was checked

try something like this
if (isset ($submit)) {
    foreach ($_POST['cb'] as $id => $val) {
        echo "$id - $val <br />";
<form method='post'>
<input type="checkbox" name="cb[id1]" value="1">  1 <br/>
<input type="checkbox" name="cb[id2]" value="2">  2 <br/>
<input type="checkbox" name="cb[id3]" value="3">  3 <br/>
<input type="submit" name="submit" value="Submit">

from what i understand, 'id' can be used instead of 'name' for client side stuff, like destinations for links, referencing an element, applying a particular style to the element with a style sheet, but it will not be posted to the server; only 'name' will.
