[SOLVED] IF statements not working

[HowdeeDoodee]

My IF statements are not working as I need them to work. Every varible in the sub= statement has to be filled with something. If the variables are filled with nothing, then the script does not work. The variables come into the script from a form. I have fundamental errors in how I have put the IF statements together. The echo'd result is  ||||||crm instead of power | peace | fill_3 | fill_4 | fill_5 | fill_6 | crm

 

Thank you in advance for your input and for any help given.

 

$A = 'power';
$B = 'peace';
$C = ' ';
$D = ' ';
$E =  '';
$F = ' ';
$G = ' ';


If ($A = ' '){
$A='fill_1';
}
If ($B = ' ' ){
$B='fill_2';
}
If ($C = ' '){
$C='fill_3';
}
If ($D = ' '){
$D='fill_4';
}
If ($E = ' '){
$E='fill_5';
}
If ($F = ' '){
$F='fill_6';
}
$G = 'crm';

$sub = $A  . '|'  .  $B  .  '|'  .  $C  .  '|'  .  $D  .  '|'  .  $E . '|' .  $F . '|' .  $G;

echo $sub;

 

This is the echo'd result.

 

||||||crm

you should use "==" on if statements, "=" is a equality sign

 

ex.

 

<?php
IF($A == ' '){
$A='fill_1';
}
?>
