[SOLVED] Simple question about a drop down list

Stagnate · November 22, 2007

Hey guys, im just starting out with PHP and im making a website that hosts some images. Its going great so far but I want to have a drop down that can show my albums.

such as:

<option value="#" selected="selected">Browse</option>

<option value="#">Ground - Concrete</option>

<option value="#">Grass</option>

<option value="#">Metal</option>

<option value="#">Graffiti</option>

</select>

</form>

I want the entrys for this to come from my images folder. For example if i have images/holiday then holiday will come up in the list.

Is there anywhere I can get an example of this?

do you mean you want the drop down list to include a list of all the images?

or do you want the drop down list to show the image selected?

since you use jump menu you will also need get variable where you will pass the name or id of each images to be displayed

if you mean that you want the select box to include the names of all your images,

this will work....

<?php
$ruff = glob("images/**");

$x = 0;

foreach($ruff as $no => $yea){
$strip = explode("/", $yea);
$content[$x] = $strip[1];
$x++;
}

$y = 0;

foreach($content as $noth => $yup){
$anoth = explode(".", $yup);
$real[$y] = $anoth[0];
$y++;
}

$holder = "          <form name=\"form\" id=\"form\">\n";
$holder .= "<select name=\"jumpMenu\" class=\"dropdown\" id=\"jumpMenu\" onchange=\"MM_jumpMenu('parent',this,0)\">\n";

foreach($real as $file => $name){
$holder .= "\t<option value=\"#\">$name</option>\n";
}

$holder .= "</select>\n";

$holder .= "</form>\n";

echo $holder;

?>

Na i dnt want the drop down to include images. Just the folder names. Heres what I mean

/images/

/Holidays/Xmas2007/Family/Boating/

So, where i have holidays/xmas..... they will be sub folders (of images) containing images in my root directory. All i need to do is for that drop down to list those folders.

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<script type="text/javascript">
<!--
function MM_jumpMenu(targ,selObj,restore){ //v3.0
  eval(targ+".location='"+selObj.options[selObj.selectedIndex].value+"'");
  if (restore) selObj.selectedIndex=0;
}
//-->
</script>
</head>

<body>
<form name="form" id="form">
        <select name="jumpMenu" class="dropdown" id="jumpMenu" onchange="MM_jumpMenu('parent',this,0)">
   		<option value="#" selected="selected">Browse</option>
        <option value="#">text</option>
  </select>
</form>
</body>
</html>

Once i get this going ill be set

Try this

i found the recursive function under the glob docs

http://www.php.net/manual/en/function.glob.php

and adopted it to what you are looking for

<?php ob_start();
session_start();

function listdirs($dir) {
    static $alldirs = array();
    $dirs = glob($dir . '/*', GLOB_ONLYDIR);
    if (count($dirs) > 0) {
        foreach ($dirs as $d) $alldirs[] = $d;
    }
    foreach ($dirs as $dir) listdirs($dir);
    return $alldirs;
}

$folder = 'images';
$dirlist = listdirs($_SERVER['DOCUMENT_ROOT'].$folder);

echo <<<htmltext
<form name="form" id="form">
        <select name="jumpMenu" class="dropdown" id="jumpMenu" onchange="MM_jumpMenu('parent',this,0)">
htmltext;
for ($i=0;$i < count($dirlist);$i += 1)
{
echo "<option value=\"".basename($dirlist[$i])."\">".basename($dirlist[$i])."</option>";
}
echo <<<htmltext
  </select>
</form>
htmltext;
?>

Ok that one doesnt show the folder names :S closeer I think, though

BenInBlack · November 22, 2007

interesting... what is your OS that web server is on, on mine it is Linux

and and so this show the folders i have in my images folder that is one off the root of my site /

if you have no subfolders in the /images folder it will show nothing.

if you are on windows then you will need to flip the / to \\

Ok that might do the trick (its XP). I'll give that one a go

Stagnate · November 22, 2007

Alright money, thats worked .

Thanks for your help everone... onto the next issue :S

BenInBlack · November 22, 2007

you will have to adjust the path reference in the function also

$dirs = glob($dir . '\\*', GLOB_ONLYDIR);

Stagnate · November 22, 2007

oh yup, seemed to work without doing that but I changed it anyway.

Im completely lost for the next part but I think I just need to hit the books

BenInBlack · November 22, 2007

books, you don't need waste money on any books,

just use these 2 urls

http://www.php.net/manual/en/index.php

and

http://www.google.com (when in google preface your queries with "PHP")
