form validating

[chris_rulez001]

hi im making a forum hosting sevice, and i would like to know how do i make it so if the checkbox is unticked they cant register.

 

heres what i have:

 

<?php
$tos = $_POST['tos'];

if ($tos == "Unchecked" || $tos == "")
{
//the code carries on

 

is the above how you would check if the checkbox is unticked?

[pedrobcabral]

if the checkbox is diferent from "on" it is not ticked.

if the checkbox is diferent from "on" it is not ticked.

 

i dont understand what you mean

[teng84]

use the isset

 

if (isset($_POST['chk'])){

then do anything here

}

[pedrobcabral]

Right, you just want also to put a ! before the word "isset".

try this to get the concept correct ok.

<?php

if(isset($_POST['submit'])){

if(empty ($one)){

echo "<br><br>unchecked 1<br><br>";

}else{

echo "<br><br>checked 1<br><br>";
}


if(empty ($two)){

echo "<br><br>unchecked 2<br><br>";

}else{

echo "<br><br>checked 2<br><br>";
}


if(empty ($three)){

echo "<br><br>unchecked 3<br><br>";

}else{

echo "<br><br>checked 3<br><br>";
}


if(empty ($four)){

echo "<br><br>unchecked 4<br><br>";

}else{

echo "<br><br>checked 4<br><br>";
}

}
?>


<form method="POST" action="<?php echo $_SERVER['PHP_SELF'] ?>">
<br><br>
check box 1
<input type="checkbox" name="one">
<br><br>
check box 2
<input type="checkbox" name="two">
<br><br>
check box 3
<input type="checkbox" name="three">
<br><br>
check box 4
<input type="checkbox" name="four">
<br>
<br>
<input type="submit" name="submit" value="cheek">
</form>

Wouldn't your example require register globals to be enabled?
