Typo. Of course.

That tip was worth its weight in gold to me! In fact, it told me where one of the typos was that was causing a syntax error during the initial parsing. The other typo was more insidious (trying to use count() as $count()), but just as deadly to the output. Thanks for the great tips!

If so, I have seen that it will not throw parse errors - it will just show a blank page. And believe me, this has caused me a huge deal of frustration. If this is the case, you may consider using an editor that has syntax validation built in. HTH ~Philip

Re: [PHP] Problem retrieving $_POST values
Hi Chris: > Exactly as you have there. > > print_r($_POST); > > will show you everything. Here's a section of what comes back when I do this: [mls] => 1234567 [property_address] => Main St [city_arr] => Array ( [0] => CHNDHT [1] => CHNDLR [2] => GILBER [3] => HIGLEY [4] => MESA [5] => TEMPE ) > How are you creating the field in your form? The three fields mentioned above on the form are specified thus: MLS#: Address: City: CHNDHT CHNDLR GILBER HIGLEY MESA TEMPE > > Is there some (free ) way to test a php script outside of a web page? > > cmd line you can do: > > php -l /path/to/file.php Is this something I can access through SSH? And will it show me errors as the script executes? Thanks for the suggestions! Jon

Hi all:
I'm having problems retrieving an array value that should be in a $_POST
setting. In fact, I'm having trouble with the code hanging with no warnings or
errors whatsoever, so I've got no clue why it's not working.
Working code:
if(isset($_POST["mls"])) {
if(strlen(trim($_POST["mls"])) > 0) {
$query = "mls=" . $_POST["mls"];
}
}
Non-working code:
if(isset($_POST['city_arr'])) {
// This space intentionally left blank.
}
The only thing I know that is different is that "mls" is a single value and that
city_arr is an array. I have tried expressing it as "city_arr[]" with no success.
Does anyone have an example of how to reference the $_POST value when said
value is an array? I can't seem to find a sample of this anywhere in the
manual.
Exactly as you have there.
print_r($_POST);
will show you everything.
How are you creating the field in your form?
Is there some (free ) way to test a php script outside of a web page?
cmd line you can do:
php -l /path/to/file.php

While I'm on the subject, how can I get a php page to tell me where a
syntax error exists if one does instead of just giving me a blank page? Is
there some (free ) way to test a php script outside of a web page?
Thanks!
Jon
