Question

ANSWER FOUND: I am reading all and deciding, THANK YOU SOO MUCH hahaha 😀 I <3 stackoverflow

I apologize for the vagueness of this question and the lack of research, but I really had no idea how to google this question.

I am passing a bible verse and bible chapter into a page that takes it and pulls the verse from the bible db likes this

?book=Genesis&chapter_number=1&verse_number=1

But what I want to be able to do is send in multiple verses separated by a “-“

like this:

?book=Genesis&chapter_number=1&verse_number=1-2

I don’t really know how this would work. Any ideas?

Answer 1

This works. It allows you to give a range of verses like 1,3,4-10. It’ll return the whole chapter if no specific verses are given.

// Get the book and chapter
$book = isset($_GET['book'])?(string)$_GET['book']:'';
$chapter = isset($_GET['chapter'])?(string)$_GET['chapter']:'';

// Make sure you escape the string to prevent SQL injection
$book = mysql_real_escape_string($book);
$chapter = mysql_real_escape_string($chapter);

// Get the verses as a string. 
$verses = isset($_GET['verses'])?trim($_GET['verses']):'';

if ($verses ==='') {
    // If no verses are given, TRUE will trick the database 
    // into returning all verses for the given book.
    $verseWhere = 'TRUE';
} else {
    // Split it on the commas
    $verseRanges = explode(',', $verses);
    $verseConditions = array();

    // Split each value on '-', if any
    foreach($verseRanges as $verseRange) {
        $verseRange = explode('-', $verseRange);
        // Build a condition
        if (count($verseRange) === 1) {
            $verseConditions[] = "verse = ".(int)$verseRange[0];
        } else {
            $verseConditions[] = "verse BETWEEN ".(int)$verseRange[0]." AND ".(int)$verseRange[1];
        }
    }

    // Implode the array to build a list of conditions
    $verseWhere = "(".implode(' OR ', $verseConditions).")";
}

// Create the SQL statement
$query = "
    SELECT 
        * 
    FROM 
        Bible
    WHERE
        book = '$book' AND
        chapter = '$chapter' AND
        $verseWhere";

[edit]
Made some minor changes, removed the typo’s and actually run the script to test it. 🙂
