One thumb - several largesize

The problem:

In CP images special only the first thumb of all is to be displayed. All large pictures should be visible in the LightBox using (next/prev).

Frontend:

Only the first thumb is visible, all other are hidden.


Solution V1:

Up to version 1.4.5 r401

The Thumbs is laid on top of each other simply with positon: absolute;.

  1. The Thumbs is laid on top of each other simply with positon: absolute;.
  2. Now still a index (z-index) is missing, so that really the first Thumb stands above.
  3. In addition a small CP-trigger can be used.

Solution V2:

Up to version 1.4.5 r401

(Preset in CP-Trigger)

  1. The thumbs are marked with display: none; to hidden.
  2. Using a small CP-trigger we display: block; to the first Thumb.


Solution V3:

Since version 1.4.6 r402 with all patches, see download docu ”DEV - Versionen im ZIP Format”.

Place in template from the CP in the surrounding container into a style statement:

[PHP]if ('{FIRST}' == '') echo 'display: none;';[/PHP]

“display: none” is set for all <div> enclosing container, except the first.

E.g. in a “Images special” template:

<!--IMAGES_ENTRY_START//-->
<div id="img{IMGID}" class="imageEntry" style="float:left;padding:5px;border:1px solid #CCCCCC;margin:{SPACE}px {SPACE}px 0 0; [PHP]if ('{FIRST}' == '') echo 'display: none;';[/PHP]">
    {IMAGE}
    [CAPTION]<p>{CAPTION}</p>[/CAPTION][CAPTION_ELSE]<p>{IMGNAME}</p>[/CAPTION_ELSE]
    [INFOTEXT]
        <!-- auto <p>info text</p> text -->
        {INFOTEXT}
    [/INFOTEXT]
    [INFOHTML]
        <!-- pure HTML info text -->
        {INFOHTML}
    [/INFOHTML]
</div>
<!--IMAGES_ENTRY_END//-->

The number of columns in BE must be at least as large as the number of images, since the ID (FIRST) = <!-- First Image --> will be placed on a column top.

There are no more scripts needed.
