[How-to] Add a multiselect field in vBulletin options
by
23 Sep 2008
I wrote this article 'cause I didn't found anything else but it was needed for mod I wrote.
Before I start - will have to say this is an example for a forumchooser.
In our product under options, create an option like this:
PHP Code:
<setting varname="your_setting_varname" displayorder="1">
<datatype>free</datatype>
<optioncode>multiselect:eval
$options = construct_forum_chooser_options(1);</optioncode>
<defaultvalue>0</defaultvalue>
</setting>
I'll use: multiselect:eval.
Ok, we finished our first part and need 2 new plugins.
The first plugin we used is admin_options_print.
PHP Code:
<plugin active="1" product="yourproduct">
<title>expand options for multiselect</title>
<hookname>admin_options_print</hookname>
<phpcode><![CDATA[if (preg_match ('#^(multiselect):(eval)(\r\n|\n|\r)(.*)$#siU', $setting['optioncode'], $matches))
{
$options = null;
eval ($setting['optiondata']);
// this is for multiselect options
$title = $description;
$array = construct_forum_chooser_options (0);
$selected = explode (',', $setting['value']);
$name .= "[]";
$htmlise = 0;
$size = 10;
$multiple = true;
global $vbulletin;
$uniqueid = fetch_uniqueid_counter ();
$select = "<div id=\"ctrl_$name\"><select name=\"$name\" id=\"sel_{$name}_$uniqueid\" tabindex=\"1\" class=\"bginput\"" . iif($size, " size=\"$size\"") . iif($multiple, ' multiple="multiple"') . iif($vbulletin->debug, " title=\"name="$name"\"") . ">\n";
$select .= construct_select_options ($array, $selected, $htmlise);
$select .= "</select></div>\n";
print_label_row ($title, $select, '', 'top', $name);
$handled = true;
}]]></phpcode>
</plugin>
See the code above and take a look at this three lines:
$array = construct_forum_chooser_options (0);
$selected = explode (',', $setting['value']);
$name .= "[]";
The 1st line are our options array, filled with information coming from the function "construct_forum_chooser_options(0)". If you wanna have your own, create an array with your options.
2nd line: our value (saved later in the options will implode by a comma like: 5,8,11,26,.. we need to explode this value to get the selected values back.
3rd line: this is needed for multiselect
The next plugin is called: admin_options_processing.
PHP Code:
<plugin active="1" product="yourproduct">
<title>save our multiselect values</title>
<hookname>admin_options_processing</hookname>
<phpcode><![CDATA[
if (preg_match ('/multiselect/i', $oldsetting['optioncode']))
{
if (is_array ($settings["$oldsetting[varname]"])) $settings["$oldsetting[varname]"] = implode (',', $settings["$oldsetting[varname]"]);
}]]></phpcode>
</plugin>
This plugin will implode our selected values with a comma.
