Need help with this php code?

Question

what i am trying to do with this code is make the echo only appear if the user has a user level of 1, 2 or 3 if they have any other user level then nothing appears. Level 1 is admin level 2 is moderator and level 3 is help desk operator. here is the code;

<?php

logincheck();

$username=$_SESSION['username'];

{

if($info->userlevel=='1')

if($info->userlevel=='2')

if($info->userlevel=='3')

echo "

<tr>

<td bgcolor='#000000'><img src='images/arrow.gif'> <a href=\"staffcentre.php\" target=\"main\"><b>Staff Centre</a></td>

<tr>";

}

?>

thanks for any help

Answer 1

You would need to complete some If checks for that, there is a pretty good Tutorial explaining how to work with If Statements at Brugbart.

http://www.brugbart.com/Tutorials/9/ - If Then, Else, ElseIf

But note, you should not use deprecated attributes such as bgcolor, and you should not use tables for layout. Its much easier to deal with CSS based layouts.

Example:

-----StartCode-----

&lt;?php

$U_level = 1;

if ($U_level == &#039;1&#039;) {

  echo &#039;You are level 1&#039;;

} ElseIf ($U_level == &#039;2&#039;) {

  echo &#039;You are level 2&#039;;

} ElseIf ($U_level == &#039;3&#039;) {

  echo &#039;You are level 3&#039;;

} Else {

  echo &#039;you are level 0&#039;;

}

?&gt;

-----CodeEnd-----

In your case it would be something like below:

-----StartCode-----

function logincheck() { // StartFunc

global $info;

if ($info == &#039;1&#039; || &#039;2&#039; || &#039;3&#039;) {

echo &#039;&lt;tr&gt;&lt;td style=&quot;background: #000000;&quot;&gt;&lt;img src=&quot;images/arrow.gif&quot;&gt; &lt;a href=&quot;\staffcentre.php&quot;&gt;Staff Centre&lt;/a&gt;&lt;/td&gt;&lt;tr&gt;&#039;;

} Else {

  // Doing nothing

}

} // EndFunc

-----StartCode-----

You need to declare the $info variable as global, before you can use it in your function.

The content of $info would be output from the database, containing the level of the specific user. Of cause you will need to combine the above with your real logged in check.

Answer 2

&lt;?php

logincheck();

$username=$_SESSION[&#039;username&#039;];

if($info-&gt;userlevel== &#039;1&#039; || &#039;2&#039; || &#039;3&#039;){

echo &quot;

&lt;tr&gt;

&lt;td bgcolor=&#039;#000000&#039;&gt;&lt;img src=&#039;images/arrow.gif&#039;&gt; &lt;a href=\&quot;staffcentre.php\&quot; target=\&quot;main\&quot;&gt;&lt;b&gt;Staff Centre&lt;/a&gt;&lt;/td&gt;

&lt;tr&gt;&quot;;

}
