Preserved Topic: Variable reset to ""

Yes!!

Why my variable $img1 gets the '' (empty) value after a query?
The query is here:

$query_select = "select img1,thumb1,img2,thumb2,img3,thumb3,img4,thumb4 from post where ID = " . $id . "";

					$result_select = mysql_query($query_select, $link);

					$num_posts = mysql_num_rows($result_select);

					while ($row = mysql_fetch_array($result_select)) {

					if (($img1 = "") && (file_exists("/inlander/sites/parejasliberales-com/web/htdocs/guest/".$row[0].""))) {

					unlink ("/inlander/sites/parejasliberales-com/web/htdocs/guest/".$row[0]."");

					unlink ("/inlander/sites/parejasliberales-com/web/htdocs/guest/".$row[1]."");

					}

}

And i need that variable for later!
I made a test to seee where the variable gets reset (I added the 'echo $img1;' line part by part) and it keeps its value till it arrives to the conditional, after that, it's empty.

The conditional is not executed, due to the $img1 variable is not empty!

do I make myself clear?

Edit: Oh!! the variable $img1 comes from a form in other page.... (post method)

don't hit your head too hard, but you put

if (($img1 = "")

gotta put ($img1 == "")



edit: oh you prolly wanted != ... either way. you get me.

If I do that, it execute the conditional! even if the variable is not "".....

Uh... guess not.

$img1 is NOT recovered from database, it comes from a text box in a formulary!

Then, i want to make some database stuff only if the variable is empty (the text box in the formulary)
The variable comes ok to the proccess page, but when this conditional into the while stuff is executed (or not) this variable gets the '' value!
