To add a lightbox to your images, add rel="lightbox" attribute to any link tag to activate the lightbox. For example:

<a href="image-1.jpg" rel="lightbox">image #1</a>

<a href="image-1.jpg" rel="lightbox[][my caption]">image #1</a>

To show a caption either use the title attribute or put in the second set of square brackets of the rel attribute.

If you have a set of related images that you would like to group, then you will need to include a group name between square brackets in the rel attribute. For example:

<a href="image-1.jpg" rel="lightbox[roadtrip]">image #1</a>
<a href="image-2.jpg" rel="lightbox[roadtrip][caption 2]">image #2</a>
<a href="image-3.jpg" rel="lightbox[roadtrip][caption 3]">image #3</a>


There are no limits to the number of image sets per page or how many images are allowed in each set.

If you wish to turn the caption into a link, format your caption in the following way:

<a href="image-1.jpg" rel='lightbox[][<a href="http://www.yourlink.com">View Image Details</a>]' >image #1</a>

To add a lightbox slideshow to your images, add rel="lightshow[slideshowname][slide caption]" attribute to any link tag to activate the slideshow. For example:

<a href="image-1.jpg" rel="lightshow[show1]">image #1</a>
<a href="image-2.jpg" rel="lightshow[show1]">image #2</a>
<a href="image-3.jpg" rel="lightshow[show1]">image #3</a>


The title attribute in the link tag is optional. The addition of this attribute enables the display of a caption with the image displayed in the lightbox.

There are no limits to the number of slideshow image sets per page or how many images are allowed in each slideshow.

If you wish to turn the caption into a link, format your caption in the following way:

<a href="image-1.jpg" rel='lightshow[show1][<a href="http://www.yourlink.com">View Image Details</a>]'>image #1</a>

It's possible to show webpage content in the lightbox, using iframes. In this case the "rel" attribute should be set to "lightframe". Again it's possible to group the content, (e.g. lightframe[search][caption]) but in addition to that, it's possible to control some of the iframe properties. It's possible to set the "width", "height" and "scrolling" properties of the iframe. The properties are separated from the group name by a |, for example lightframe[search|width:100px;][caption]. If no grouping is being used, then the | is still used and the format would be lightframe[|width:100px;]. The properties should all be of the format "property: value;" - note the closing semi-colon. If no iframe properties are set, then the default width and height of 400px will be used. See below for more detailed examples.

Basic example:
<a href="http://www.google.com" rel="lightframe">Search google</a>

Grouped example:
<a href="http://www.google.com" rel="lightframe[search][caption]">Search google</a>
<a href="http://www.yahoo.com" rel="lightframe[search]">Search yahoo</a>

Controlling iframe property example:
<a href="http://www.google.com" rel="lightframe[|width:400px; height:300px; scrolling: auto;][caption]">Search google</a>

Controlling iframe property when grouped example:
<a href="http://www.google.com" rel="lightframe[search|width:400px; height:300px; scrolling: auto;]">Search google</a>
<a href="http://www.yahoo.com" rel="lightframe[search|width:400px; height:300px;]">Search yahoo</a>

It's possible to show video content in the lightbox. In this case the "rel" attribute should be set to lightvideo. It's possible to group videos and to control the size of the lightbox by setting the "width" and "height" properties. The properties can be configured like lightvideo[group|width:300px; height: 200px;][caption]. The properties should all be of the format "property: value;" - note the closing semi-colon. If no properties are set, then the default width and height of 400px will be used. See below for more detailed examples.

Basic example:
<a href="http://video.google.com/videoplay?docid=1811233136844420765" rel="lightvideo">Google video example - default size</a>

Controlling lightbox size example:
<a href="http://video.google.com/videoplay?docid=1811233136844420765" rel="lightvideo[group|width:400px; height:300px;][caption]">Google video example - custom size</a>

Supported video formats include asx, wmv, mov and swf. A number of online video providers are also supported, including YouTube and Google Video. For a full list of the current supported video providers please see the documentation on drupal.org.

It's possible to show HTML snippets in the lightbox, that is on the same domain. In this case the "rel" attribute should be set to "lightmodal". Again it's possible to group the content, (e.g. lightmodal[group][caption]) but in addition to that, it's possible to control some of the modal properties. It's possible to set the "width", "height" and "scrolling" properties of the modal. The properties are separated from the group name by a |, for example lightmodal[group|width:100px;][caption]. If no grouping is being used, then the | is still used and the format would be lightmodal[|width:100px;]. The properties should all be of the format "property: value;" - note the closing semi-colon. If no modal properties are set, then the default width and height of 400px will be used. See below for more detailed examples.

Basic example:
<a href="search.php" rel="lightmodal">Search</a>

Grouped example:
<a href="search.php" rel="lightmodal[search][caption 1]">Search</a>
<a href="search.php?status=1" rel="lightmodal[search]">Search published</a>

Controlling modal property example:
<a href="search.php" rel="lightmodal[|width:400px; height:300px; scrolling: auto;][caption]">Search</a>

Controlling modal property when grouped example:
<a href="search.php" rel="lightmodal[search|width:400px; height:300px; scrolling: auto;]">Search</a>
<a href="search.php?status=1" rel="lightmodal[search|width:400px; height:300px;]">Search published</a>

Brug tilpasset PHP-kode

PHP-koden kan indlejres i visse typer af indhold, inklusiv indlæg og blokke. Selvom indlejret PHP øger fleksibiliteten for betroede brugere, er der stor sandsynlighed for at det kan bringe sikkerheden i fare hvis det ikke anvendes korrekt. Selv små fejl i PHP-koden kan have store konsekvenser for dit site.

Hvis du ikke er bekendt med PHP, SQL og Drupal, bør du undgå at bruge PHP i indlæg. Eksperimenter med PHP kan ødelægge din database, gøre dit site ubrugeligt og bringe sikkerheden i fare.

Bemærkninger:

• Husk at gennemgå hver linje for syntaks- og logikfejl før du gemmer.
• Udtryk skal afsluttes med semikoloner.
• Globale variable i din PHP-kode beholder deres værdi, efter din kode er blevet udført.
• register_globals er slået fra. Hvis du har behov for at bruge formularer, skal du bruge funktionerne fra Drupals Formular-API.
• Brug et print eller return udtryk i din kode for at udskrive indhold.
• Du bør udvikle og teste din PHP-kode i et separat test-script og en separat database før du sætter den i produktion.
• Du bør overveje at indsætte din PHP-kode i et site-specifikt modul eller template.php i stedet for at skrive den direkte i en blok eller et indlæg.
• Vær opmærksom på at muligheden for at indlejre PHP-kode i indholdet stilles til rådighed af PHP Filter-modulet. Hvis modulet er deaktiveret eller slettet, vil blokke og indlæg med indlejret PHP vise PHP-koden i stedet for at fortolke den.

En simpelt eksempel: Opret en "Velkommen"-blok som hilser besøgende med en simpel besked.

• Tilføj en blok med navnet "Velkommen" til dit site. Sæt dens format til "PHP-kode" (eller et andet format som understøttet PHP) og tilføj følgende kode til indholdet:

  print t('Velkommen gæst! Tak fordi du kigger forbi.');
  

• For at vise navnet på en registreret kan du bruge følgende kode i stedet:

  global $user;
  if ($user->uid) {
    print t('Velkommen @name! Tak fordi du kigger forbi.', array('@name' => $user->name));
  }
  else {
    print t('Velkommen gæst! Tak fordi du kigger forbi.');
  }
  

Drupal.org tilbyder PHP eksempler, eller du kan lave dine egne hvis du har erfaring med PHP og viden om Drupal.
