Help me (PHP)

[Monk3h]

Right, this Code 'Should work' and yet dosnt.. Its the PHP and not the SQL because instead of just displaying the 'else' Part of the code when i have Gembag as s it still displays the first bit. Now i know it gives me the gembag and changes it to 's' from 'n' in the database but it still only shows the first if part of the code and not the else. :s

 

<?php $title = "Gem Store"; include("header.php"); ?>

<b>Store Owner:</b> Welcome to my store! Here you can <i>Buy</i> and <i>Sell</i> many diferent Priceless Stones..<br><br><br> 

<?php
if ($stat[gembag] = n ) {

	Print "<b>Store Assistant:</b> You dont appear to have a <i>Gem Bag</i>! How do you expect to collect all the precious stones that are available in this wonderful Town?<br><br>";

	Print "<b>Store Assistant:</b> Here, take this.. Its on the house, but dont get telling people we do FreeBs!<br><br>";

	Print "The store Assistant hands you a <b>Small Gem Bag</b>";

mysql_query("update players set gembag='s' where id=$stat[id]");

include("footer.php");
exit; } 


else {
		Print "<b>Store Assistant:</b> How are you getting on with that <i>Small Gem Bag</i>? Normally you could upgrade that tiny thing! (For a Small Fee) But right now we are out of Stock.";

include("footer.php");
exit; }

?>
<?php include("footer.php"); ?>

Watch out for your if statements.  if ($something = $somethingelse) { will return true.  Add the double ==.

 

if ($stat[gembag] == n ) {

W00t.. Works now, Thanks dude!

 

So Why do i need the Double == whats the diference? :S

[AndyB]

= is the assignment operator

== is the equality operator

 

They are (obviously) not equivalent.

if ($something = $somethingelse) { will return true.

 

Not if $something else contains 0 or false.
