[Resolved] How to get $PHP_SELF to resovle in this

[chucklarge]

Hi,

I am sure it is something simple, but how do i get PHP_SELF to resolve in this ?

echo '<form id="keyword_input" method="post" action="$PHP_SELF">';

right now, it actually puts "$PHP_SELF" instead the the file like "file.php'

Thanks,
Chuck

echo "<form id=\"keyword_input\" method=\"post\" action=\"".$_SERVER['PHP_SELF']."\">";

Well, two things to correct here. You're using single quotes, and variables aren't parsed inside them. Also, you're using $PHP_SELF, which you should hope does not exist. If it does, you're using register_globals, which you shouldn't, unless you know what you're doing (and in that case, you'd probably just turn it off). You should instead be using $_SERVER['PHP_SELF'] as TheDefender pointed out.

However, the line he gave you should give you a parse error. Instead, concatenate the variable with the echoed string:
'<form id="keyword_input" method="post" action="' . $_SERVER['PHP_SELF'] . '">'

But, if we look up echo, it takes multiple arguments. Thus, we can simply:
echo '<form id="keyword_input" method="post" action="', $_SERVER['PHP_SELF'], '">';

Voila.

Another way

echo "<form id=\"keyword_input\" method=\"post\" action=\"{$_SERVER['PHP_SELF']}\">";

Put curly braces around the variable in this case.

This one works, too (at least on my server):

echo "<form id=\"keyword_input\" method=\"post\" action=\"$_SERVER[PHP_SELF]\">";

Without single quotes around the index of the array.

D'OH! Thanks Mordecai and Tsinka... I have corrected mine above to the method I would use personally... Thanks again for the calibration. 😉
