How to use jquery variable in php same page without submitted the form [duplicate]

Question

I'm trying to pass a Jquery variable to a php variable on the same page when the list item changed

<select name="RegistrationTypeID"class="formselectbox"id="RD"
onchange="getText(this.val)">

<option value="">Select Registration Type</option>                                               
<option value="1">Contractor</option>
<option value="2">Exhibitor</option>
<option value="3">Media</option>
<option value="4">Organizer</option>
<option value="5">VIP</option>
<option value="6">Visitor</option>                                           
</select>

function getText(text){

var a = $("#RD option:selected").text();

  // i want variable  a to `php` variable a. on same page  
}

Also take care with the spaces in and around your attributes — mplungjan

This can be done by creating a http request to your php page like so:

var a = $("#RD option:selected").text();
$.get( "test.php", { variable: a } );

What you do here is send a request to the php file with a parameter named variable with the value of a.

In your php you need to store the data this you can do with sessions

So we can use $_GET to get this variable as a php variable after using $.get( "test.php", { variable: a } );

my page URL is coded so we think we should use $(location).attr('href'); localhost/event_registration/admin/index.php?0/…

You could use that or the plain js way window.location.href
