addnew.php code

Expand|Select|Wrap|Line Numbers

 <? php

 if( isset($_POST['da']) ) 

 {

       echo (da);

  }

?>

when page is rendered will have like this.

<textbox1 data> <add button>
<textbox1 data> <add button>
<textbox1 data> <add button>
...
<textbox10 data> <add button>

what I am trying is

1. Created each textbox and add button pair inside each form dynamically using for loop.
(for testing i created only one pair).Should I have form for every pair?
2. when add is clicked value within textbox (#da) should be send to addnew.php through ajax.

following code is displaying data correctly

Expand|Select|Wrap|Line Numbers

alert(da);

but in addnew.php file I am not getting $_POST(['da']). Is that means data is not passed to the file or is there something wrong ajax code and finally can I have multiple form with same id. If not then how i can send the only one textbox data ie just before the add button when form is submitted.

Usually when a method isn't set in <form> tags, it defaults to get. Set the method to post in the form tag.

your line 29 is completely wrong

only data is going

Expand|Select|Wrap|Line Numbers

data:da,

which mean only value but no variable name. Do this

Expand|Select|Wrap|Line Numbers

data:"da="+da,

you will get post data properly
