in the other page (rmq-demande.php) here is how i wanted to get the variable $idd:

$dem=$_POST['id_demm'];

but it gets nothing plz help

-------------Problems Reply------------

You can do it in 2(two) way:-

1. remove link and create submit button like below:-

echo "
<form name=\"theform\" method=\"post\" action=\"rmq-demande.php\">
<input type=\"hidden\" name=\"id_demm\" value=\"$idd\">

<span class=\"contacts-title\">$title</span>
<p>$dem</p>
<input type = \"submit\" name= \"submit\" value=\"submit\" >
</a> </form>";

  1. Or remove form and append id into link like below:-

    echo "<a href=\"rmq-demande.php?id_demm=$idd\" class=\"list-group-item\" target='_blank'>
    <span class=\"contacts-title\">$title</span>
    <p>$dem</p>";

But for getting id through this in php you need to do like this:-

$dem=$_GET['id_demm'];

Note:- first way is more secure. thanks
