Good day all:

I want to get the value of a textbox into php without clicking the submit button. Any advice... Here is what I have
My form field:


#1
<input type="text" style=background:transparent; border:0px; name='clientid' >


This field is populated dynamically by its name with another php script in this way

#2
echo "formObj.clientid.value = '".toSafeString($inf["clientID"])."';\n";


Now I want to take the value in code#1 (name='clientid') and pass it to a php code that is in the same file as the form. Here is the php code


<?php
$name=$_POST['name'];//this is where the value of the text box mentioned is defined
include 'datalogin.php';

error_reporting(0);
error_reporting(E_ERROR | E_WARNING | E_PARSE);
//test
//get image details
$uploaddir = "images/clientsimages/";

$get_data = "SELECT i.uploadedfile, i.clientid " . " FROM images AS i, ajax_client AS a " . " WHERE i.clientid = a.clientID " . " AND a.clientID = $name";

$get_data_res = mysql_query($get_data) or die(mysql_error() . '<br>sql : '.$get_data);

if (mysql_num_rows($get_data_res) > 0)
{
while ($get_data_info = mysql_fetch_array($get_data_res))
{
$uploadedfile = $uploaddir . $get_data_info["uploadedfile"];


}
}

?>


I know this may require js, but I appreciate any help!

Search Google for AJAX examples as you will need AJAX to allow Javascript and PHP to communicate and do the job you want it to do.

Thanks for the reply. I'm not using js currently. My question is whether I can use js to be able to get the textbox input value from the form to php code?

And you got the answer. AJAX. Period. There's no other way.

You might start here:
http://www.w3schools.com/php/default.asp

Look down the page to the category "PHP and AJAX".

Be prepared to start learning JavaScript.
