PHP Array Search

Alpha · 10-25-2003, 02:27 PM

Ok I am asking for someone to please look this over:

PHP Code:

  <?php

$subjects = array(0=>"Calculus", 1=>"Physics", 2=>"Study Skills", 3=>"Band", 4=>"English", 5=>"PE");

$search = $POST_['search'];

//Search the array $subjects for the value $search.

$limit = count($subjects);

for ($i=0; $i<$limit; $i++)

{

    echo "<BR>Searching for a match with $subjects[$i]";

    

    if($search == "$subjects[$i]")

    {

        echo "<BR>$search is one of my classes.";

        break;

    }

}

?>

This code goes with the small HTML form:

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE> Class Searcher</TITLE>
</HEAD>
<BODY>
<FORM METHOD="POST" ACTION="subjectsarray.php">
Search for:<INPUT TYPE="TEXT" NAME="search">
<INPUT TYPE="SUBMIT" VALUE="Search">
</FORM>
</BODY>
</HTML>

What I want it to print when I search for Study Skills is:
????: NamePros.com http://www.namepros.com/programming/15455-php-array-search.html
Searching for a match with Calculus
Searching for a match with Biology
Searching for a match with Study Skills
School Success is one of my classes.

But what it prints is:
Searching for a match with Calculus
Searching for a match with Biology
Searching for a match with Study Skills
Searching for a match with Band
Searching for a match with English
Searching for a match with PE

However, the similar code:

PHP Code:

  <?php

$languages = array(0=>"Perl", 1=>"PHP", 2=>"Python");

$search = "PHP";

// search the array $languages for the value $search

$limit = count($languages);

for ($i=0; $i<$limit; $i++)

{

    echo "<BR>Testing for match with $languages[$i]";

    if ($search == $languages[$i])

    {

        echo "<BR>$search is an approved language.";

        break;

    }

????: NamePros.com http://www.namepros.com/showthread.php?t=15455
}

?>

(which does not use a form)
Works just fine. Anyone know what I am doing wrong?

If you add an if statement so it looks something like this:

PHP Code:

  <?php 

$subjects = array(0=>"Calculus", 1=>"Physics", 2=>"Study Skills", 3=>"Band", 4=>"English", 5=>"PE"); 

$search = $POST_['search']; 

//Search the array $subjects for the value $search. 

$limit = count($subjects); 

if ($search) {

for ($i=0; $i<$limit; $i++)

????: NamePros.com http://www.namepros.com/showthread.php?t=15455
{

    echo "<BR>Searching for a match with $subjects[$i]";

????: NamePros.com http://www.namepros.com/showthread.php?t=15455
    

    if($search == "$subjects[$i]")

    {

        echo "<BR>$search is one of my classes.";

        break;

    }

}

}

?>

I think that will get you what you're wanting.

Thanks but now it just brings up a blank page

It's weird I don't get this at all lol. I usually try to make little programs like that as I am going thru the book so it helps me understand but boy this one is evil LOL.

deadserious · 10-25-2003, 10:55 PM

Try changine $POST_['search'] to $HTTP_POST_VARS['search'] and see if that makes a difference.

................................ IT WORKED!!!!!!! THANKS DEAD!!!!! Ok but that's still weird cuz in my other codes I dont have to put $HTTP_POST_VARS['search'] lol. Who knows PHP is evil

THANKS AGAIN!!!!!!

EDIT: ......Dead.....I don't think I'm OK. I was supposed to be putting $_POST['search'] not $POST_['search']. Thank you VERY much
