Post a Comment
hi everyone my problem is this that i dynamically creted rows of table on the basis user input. Now each row contain textbox,comboxbox on selcting value from combobox n entering va

Solution 1:

You need to be passing an array, you can deal with it as an array in the PHP side.

To do this, in each input, change the name="X" to name="X[]"

Example:

        <input type="text" name="t2" id="in1-<?php echo $i; ?>" onblur="getText3(<?php echo $i; ?>)" />

to:

        <input type="text" name="t2[<?php echo $i; ?>]" id="in1-<?php echo $i; ?>" onblur="getText3(<?php echo $i; ?>)" />

Also, it's generally a bad idea to use @'s in php to suppress errors.

Try something like:

  var_dump($_POST);

and you will see how the data comes through to you.

Hint:

if (isset($_POST['t1']) {
   $t1_data = $_POST['t1'];
}

** EDIT **

Try something like this:

<?php

if (isset($_POST['submit'])) {

    $data_t1 = $_POST['t1'];
    foreach ($data_t1 as $key => $value) {

        echo 'T1: ' . $value . '<br />';
        echo 'T2: ' . $_POST['t2'][$key] . '<br />';
        echo 'Username: ' . $_POST['username'][$key] . '<br /><br />';

    }

}
?>

            var in1=document.getElementById('in1-' + row).value;
            var in2=document.getElementById('in2-' + row).value;
            var in4=document.getElementById('in4-' + row).value;
            var in3=(in1*in2*in4*30)/1000;
            document.getElementById('in3-' + row).value=in3.toFixed(2 );
