it create text box name=id1,id2,id3..... on clicking add option. when going fetch value, give error " undefined index: id2"
<script> var i=1; function myfunction() { i++; var x = document.createelement("input"); x.setattribute("type", "text"); x.setattribute("name", "id"+i); elem = document.getelementbyid("hide_specific"); elem.appendchild(x); } </script> <body> <?php $submission=""; if($_server["request_method"]=="post"){$submission=$_post["id2"];} ?> <table> <form action="" method="post"> <tr> <td> <div id="hide_specific"><input type="text" name="id1" ><span onclick="myfunction()">add</span></div> </td> </tr> <tr> <td><input type="submit" name="set" value="set"></td></tr> <tr><td> <?php echo $submission; ?></td></tr> </form> </table> </body>
checked question in localhost, , used firebug.. found form closed in table(form without dynamically created inputs,id2,id3 etc). thats why post values not getting.your script absolutely fine. try add form tag before table. code shown below
<body> <?php $submission=""; if($_server["request_method"]=="post"){$submission=$_post["id2"];} ?> <form action="" method="post"> <!-- ######### open form tag before table --> <table> <tr> <td> <div id="hide_specific"><input type="text" name="id1" ><span onclick="myfunction()">add</span></div> </td> </tr> <tr> <td><input type="submit" name="set" value="set"/></td></tr> <tr><td> <?php echo $submission; ?></td></tr> </table> </form> </body>
