Alphabetizing a textbox

jdk · 08-07-2007, 10:42 AM

I tried searching google, but didn't find anything.

I want to post data into a textbox and click a button to alphabetize the data either A to Z or Z to A

Does anyone know of a code to do such a thing?

If you can get all the pieces of data into an array, then you can do it using PHP's sort() function, example:

PHP Code:

  $names = array('lee101','jdk');

sort($names);

print_r($names);

Will output all values in the $names array alphabetically

PHP Code:

  <?php

/*

    Alphabetizes the content of a textarea on a line-by-line basis.

    Sorting is case-insensitive.

    Blank lines are removed.

*/

 
if (isset($_POST['content'])) // alphabetize everything

{

    // break the text area into lines

    $lines = explode("\n", $_POST['content']);

    

    // now remove blank lines

    function strip_blanks($val) {return trim($val) == '' ? false : true;}

    $lines = array_filter($lines,strip_blanks);

    

    // now alphabetize the array.  The array is passed as a reference,

    // and sorting is done in-situ

    natcasesort($lines);

        

    // make the list display safe

    $sorted = htmlentities(implode("\n",$lines));

}

else // initialize

{

    $sorted = '';

}

?>

Thanks both of you. I think I have what I need to make what I am trying to. I will create something else to sort in reverse order.

Oops, forgot about the reverse. That only requires one extra optional call, and another button on the form.

I'll update shortly.

With reverse sorting added:

PHP Code:

  <?php

/*

    Alphabetizes the content of a textarea on a line-by-line basis.

    Sorting is case-insensitive.

    Blank lines are removed.

    One form button for forward sorting, another for reverse sorting.

*/

 
if (isset($_POST['content'])) // alphabetize everything

{

    // break the text area into lines

    $lines = explode("\n", $_POST['content']);

    

    // now remove blank lines

    function strip_blanks($val) {return trim($val) == '' ? false : true;}

    $lines = array_filter($lines,strip_blanks);

    

    // now alphabetize the array.  The array is passed as a reference,

    // and sorting is done in-situ

    natcasesort($lines);

        

    // now see if we're reverse sorting

    if ($_POST['rsort'])

        $lines = array_reverse($lines,false);

        

    // make the list display safe

    $sorted = htmlentities(implode("\n",$lines));

}

else // initialize

{

    $sorted = '';

}

?>
