HTML Form POST is null

Solution 1
This code is working. You need to add some condition, that checks, if $username
is posted or not.
Something like that:
if(count($_POST)){
$username ='';
if(isset($_POST['user'])){
$username = $_POST['user'];
if ($username==null || !$username)
echo 'username is null';
echo strlen($username);
echo $username;
}
}

The issue is that all of your inputs have id
but not name
. The id
are used by JavaScript. The name
are used for sending form data.
Change it to be like this:
<form action='http://k9minecraft.tk/scripts/adduser.php' method='POST'>
<table>
<tr>
<td>First Name:</td>
<td><input type='text' name='first' id='first'></td>
</tr>
<tr>
<td>Last Name:</td>
<td><input type='text' name='last' id='last'></td>
</tr>
<tr>
<td>Email:</td>
<td><input type='text' name='email' id='email'></td>
</tr>
<tr>
<td>Minecraft Name:</td>
<td><input type='text' name='user'></td>
</tr>
<tr>
<td><input type='submit' name='Send' value='Send'></td>
<td><input type='reset' name='Rest' value='Reset'></td>
</tr>
</table>
</form>

Try this to find out if the field is posted by the formular:
isset($_POST['user'])
I think $username==null
will be true even if $username
really is equal to an empty string.

so I'm trying to simply send one field of data from a form to a php file. Below is my form in a table. I also posted my php code. It keeps returning that $username is null. Ive tried post/get and it doesn't seem to matter.
HTML:
<form action='http://k9minecraft.tk/scripts/adduser.php' method='POST'> <table> <tr> <td>First Name:</td> <td><input type='text' id='first'></td> </tr> <tr> <td>Last Name:</td> <td><input type='text' id='last'></td> </tr> <tr> <td>Email:</td> <td><input type='text' id='email'></td> </tr> <tr> <td>Minecraft Name:</td> <td><input type='text' name='user'></td> </tr> <tr> <td><input type='submit' value='Send'></td> <td><input type='reset' value='Reset'></td> </tr> </table> </form>
PHP:
<?php print_r($_POST); if (isset($_POST['user'])) { $username = $_POST['user']; echo $username; echo 'username is not null'; } ?>
