Getting Var into jquery .post data

JavaScript
1

Hi all

I am not a javascript programmer.

I am trying to use the jquery $.post function to send data to a php script, but Im getting stumped on how to pass a javascript variable to the data section of said function.


  <div class="qty">Qty: 
   <select id="qty<?php echo $prodid; ?>" name="qty">
    <option value="1">1</option>
    <option value="2">2</option>
    <option value="3">3</option>
    <option value="4">4</option>
    <option value="5">5</option>
    <option value="6">6</option>
    <option value="7">7</option>
    <option value="8">8</option>
    <option value="9">9</option>
    <option value="10">10</option>
   </select>  
  </div>
  <div class="basket">
   <a href="#nogo" onClick="qtyordered=document.getElementById('qty<?php echo $prodid; ?>').value; $.post('basket.php',{op:'add',prod:'<?php echo $prodid; ?>',qty:qtyordered})">
<img src="images/siteimages/basket.png" /></a>
  </div>

As you can see the onclick reads the value of the associated select box which I then need transfered to the qty element of the data.

TIA

Hi,

Try this:

<a href="#nogo" onClick="qtyordered=document.getElementById('qty<?php echo $prodid; ?>').value; $.ajax({ type: 'POST',  url: 'basket.php',  data: {op:'add', prod:'<?php echo $prodid; ?>' ,qty: qtyordered}); ">

Any joy?

Thanks Pullo

Ive since found that the fault doesnt seem to be in the javascript, its in the DB only being able to create one row, once I get that sorted I’ll come back if I have a problem with the javascript. Thanks again for your quick response.

Yeah, my appologies, the javascript works fine, my problem was Id inadvertantly made the field that stored the session ID in the DB a Primary Field, so the script worked on the first attempt, then didnt seem to work on subsequent attempts, since my first attempt used hard coded values, then I changed to the variable which seemingly then failed … so I blamed my JS skills.

Thanks again

No problems - I didn’t really do anything :slight_smile:
I’m glad you got it sorted out - thanks for taking the time to report back.
