Handle HTML form with PHP


Hi I am a newbie with PHP, and I was trying to handle an HTML Login form, when I click submit, the POST request is sent (I check with Firebug, and also in Apache access.log file), but I can't retrieve the form variables (username and password, eg: $username = _POST['username']). After searching forums, I noticed that there is a variable in php.ini: track_vars that must be enabled in order to have variable stored in POST superglobal. By default, it was not present in php.ini file, I added it and then reload apache2, but in phpinfo() it does not appear, I also added it in /etc/apache2/mods-enabled/php.conf but I still have the same problem. Here is the output of phpinfo().

Any idea is welcomed.
Thanks in advance.

Welcome to LinuxQuestions

Without seeing your code it is difficult to say if your problem is a programming error or a php configuration error. What distribution / version of linux are you running? As far a I know track_vars is always enabled.

<td>User name:</td>
<td><input type="text" size="20" class="login" id="username"></td>
</tr>
<tr>
<td>Password:</td>
<td><input type="password" size="20" class="login" id="password"></td>
</tr>
<tr>
<td class="textcenter" colspan="2"><input type="submit" id="loginButton" disabled value="login"></td>
</tr>
<tr>
<td class="textcenter" colspan="2"><a href="signup.html">Forgot password: click here</a></td>
</tr>
<tr>
<td class="textcenter" colspan="2"><a href="signup.html">New user: click here</a></td>
</tr>
</table>
</fieldset>
</form>

And Here is my PHP code:
<?php
echo "Welcome " .$_POST['username'];
?> I received a notice as the index 'username' is undefined.

I also tried:
$rawdata = file_get_contents('php://input');
var_dump($rawdata);

and with:
var_dump($_POST);

they give both empty array;

By the way, I am using Ubuntu Server 13.10 with the LAMP package.

Thanks again.

The reason you are getting the error is because id and class are not valid text box attributes. try:
<input type="text" size="20" name="username">

Same goes for the button. disabled will disable the button. Try:
<input type="submit" value="login">
