find_value() issue

**alexjewell** · 08-31-2006, 10:54 PM

Alright, it looks like we're on the right track. However, should we make $search_name global? I'm getting an undefined variable error:

PHP Code:


$names = array( "1. Alex" => "alex" , "2. Amanda" => "amanda" , "3. John" => "john" , 
                "4. Smith" => "smith" , "5. Jewell" => "alex jewell" );

$name = strtolower($_REQUEST['name']);

//array_strpos    Array    Search Value
function array_find_value($array,$svalue){
    $search_name = array();
    foreach($array as $key=>$value){
        if(stristr($value,$svalue) !== FALSE){
            $search_name[$key] = $value;
        }
    }
    return $search_name;
}

$outcome = $search_name or 'Sorry, no matches';
echo 'You searched for: <i>'.$name.'</i>.<br />'.$outcome;

ps - don't we somehow have to incorporate the $name and $names, as well?

You don't understand what the function I wrote does.I intended for it to just point you in the right direction. I should have given a better explanation than one comment. Here is a more complete example.

PHP Code:


<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

<html>

<head>

<title>Test Search</title>

</head>

<body>

<?php

//array_find_value    Array    Search Value

function array_find_value($array,$svalue){

    $return = array();

    if(empty($svalue)){

        return $array;

    }

    foreach($array as $key=>$value){

        if(stristr($value,$svalue) !== FALSE){

            $return[$key] = $value;

        }

    }

    return $return;

}

function search($array,$search){

    $find = array_find_value($array,$search);

    echo '<p>You searched for "'.$search.'". There were '.count($find).' results.</p>';

    echo ' <form method="get" action="'.$_SERVER['PHP_SELF'].'"><input type="text" name="name"><button type="submit">Search Again</button></form>';

    echo '<ol>';

    foreach($find as $key=>$value){

        echo "<li>".$key."</li>";

    }

    echo '</ol>';

}



if(!empty($_REQUEST['name'])){

    $name = $_REQUEST['name'];

}

else{

    $name = '';

}

$names = array( "Alex" => "alex" , "Amanda" => "amanda" , "John" => "john" , "Smith" => "smith" , "Jewell" => "alex jewell" );

search($names,$name);

?>

</body>

</html>
