My current ajax send params-

var params="qty="+document.table_form.elements["qty[]"]";

My PHP array fetch -

  foreach($_POST['qty'] as $value){
        if($index<=$rows){
        $clean_value=mysql_real_escape_string($value);
        $clean_value=stripcslashes($clean_value);

EDIT

I am a bonehead--you are not using jQuery. Here is some coee which iterates the inputs in a form looking for elements named qty[] http://jsfiddle.net/JAAulde/WQjQM/6/

END EDIT

Original (jQuery) Answer Below

If I have 3 inputs named qty[] with values a, b, c

Both:

var params = $.param( $( '[name="qty\[\]"]' ) );

(demo: http://jsfiddle.net/JAAulde/WQjQM/1/ )

and:

var params = $( '[name="qty\[\]"]' ).serialize();

(demo: http://jsfiddle.net/JAAulde/WQjQM/ )

give me:

qty%5B%5D=a&qty%5B%5D=b&qty%5B%5D=c

This should be correct for you.

@JAAulde Thank you for your response but I have more than 40 values with qty[].So do you have some other way to do this.

@Ceylo I fail to see why it makes a difference...have you tried it? Does it work? Is it performing ok?

@JAAulde sorry my mistake.I am new to jquery friend.Can you explain me what is above give me: string.How should I send it to php.How php get this data?.Thanx

JAAulde Over a year ago

@Ceylo no problem. Send it the same way you already are, I imagine: $.ajax( { url: '/yourPage.php', type: 'POST', data: params } );

Oh, dude, I am sooooo sorry. Based on the first answer submitted, and having seen the $ in your PHP code block, I totally effed up and thought you were using jQuery. I've misled you, let me reformulate...

You may want to look at http://api.jquery.com/serialize/ as a solution of how to send off the form values. It should work with arrays (I think)
