how to deal with bool?

[jrahma]

Hi,

I have the following code to check if the user is_administrator then show the two menu items, otherwise of course it won't show... kindly simple! but the problem is.... when I uploaded the pages to my web host, even if the user is not administrator the menu items are shown! the value for is_administrator in MySQL is a bit = 0 but when I do a var_dump I get bool(true) although I get the correct var_dump and behavior on my local pc string(1) "0"

this is the menu items:

<?php  if ((bool)$_SESSION["blended_learning_is_administrator"] = true) { ?>
<tr><td>&lt;button id="btnManageUsers" type="button" style="width: 100%;">Manage Users&lt;/button></td></tr>
<tr><td>&lt;button id="btnNewUser" type="button" style="width: 100%;">New User&lt;/button></td></tr>
<?php } ?>

and this is the is_administrator:

while ($mysql_row = $mysql_query->fetch())
{
    $_SESSION["blended_learning_user_name"] = $mysql_row["user_name"];
    $_SESSION["blended_learning_is_administrator"] = $mysql_row["is_administrator"];

exit(header("Location: " . $_SESSION["blended_learning_domain_name"] . "mypage"));
}

From the maual:
When converting to boolean, the following values are considered FALSE:

the boolean FALSE itself
the integer 0 (zero)
the float 0.0 (zero)
the empty string, and the string "0"
an array with zero elements
an object with zero member variables (PHP 4 only)
the special type NULL (including unset variables)
SimpleXML objects created from empty tags

Every other value is considered TRUE (including any resource).

((bool)$_SESSION["blended_learning_is_administrator"] = true)

You're using [font=monospace]=[/font] instead of [font=monospace]==[/font] here. The test will always succeed.
