Php – how to use $_POST in wordpress

phpwordpress

Hey i am trying to retrive data from a basic form .. but when i am using $_POST['field name'] then it gives me nothing .

here is my basic code

form page is:

<?php
/**

Template Name: galaxy
 */

get_header(); ?>

<div id="main-content" class="main-content">

<form action="<?php echo site_url();?>?page_id=8" method="post">
<input type="text" name="name"  /> <input type="submit" value="Send"  />

</form>

</div><!-- #main-content -->

<?php
get_footer();

when i click submit it redirects to next page but display nothing with this code

<?php
/**

Template Name: get_value_galaxy
 */


$name=$_POST['name'];
echo $name;

print_r($_POST);

?>

Best Solution

Try using a different name for the variable. I know that Wordpress uses "name" as a public query var, and perhaps that's why it's not working. So rather than using name="name", try this:

Form:

<input type="text" name="unique_name" />

Post Page:

$name=$_POST['unique_name'];
echo $name;

See this list for all query vars: http://codex.wordpress.org/WordPress_Query_Vars#Query_variables
