Question

I have a jQuery function to dynamically add rows containing input fields, this exists on a form, the function adds text boxes (distinct names) to each cell in the table

an example of the generated HTML would be:

<table width="400" border="0" cellspacing="0" cellpadding="2px" margin="0" >
    <tbody>
    <tr>
        <td><input type="text" name="name_1"></td>
        <td><input type="text" name="surname_1"></td>
        <td><input type="text" name="age_1"></td>
    </tr>
    <tr>
        <td><input type="text" name="name_2"></td>
        <td><input type="text" name="surname_2"></td>
        <td><input type="text" name="age_2"></td>
    </tr>
    <tr>
        <td><input type="text" name="name_3"></td>
        <td><input type="text" name="surname_3"></td>
        <td><input type="text" name="age_3"></td>
    </tr>
    </tbody>

I am reading the “$_POST[‘varName’] data with the following code:

<?php
    $cnt = 1 ;
    $fName = ( $name ."_" .$cnt) ;
    do {
        echo("$_POST[$fName]  <br>");
        $cnt = $cnt +1 ; 
        $fName = ( $fldName ."_" .$cnt) ;

        } while (isset($_POST[$fName]));
    ?>

however, i would like to simply loop through each row in the table and read the data sequentially in a loop (using PHP), my idea is to pass the table object to a php function, is this possible?

Basically i am looking for a solution to read the table data, where each row contains input boxes “name_X”, “surname_x” and “age_x” and i will not know how many rows exist at design time… (i will never have more than 9 rows)

Hope this is clear!
… Any Suggestions?

You could use a hidden field and set there the number of rows as value using javascript.
In the php script you can then use a simple for loop.

Simething like this:

$rowCount = $_POST['hiddenName'];
for($i=1; i<=$rowCount; $i++)
{

  $_POST['name_'.$i]
  ...
}
