NewsListing with seperate Image for summary page

Hi all,

first of all this is my first project with MODx and I’d like to thank all for the great documentation / support. So far I could solve most of my problems by reading and "trail an error", but now I could use some help

I need the NewsListing snippet to show images on the summary page. I tried to add a new placeholder for a TV with an image inside. But I think I messed it up


I created a TV (type image) and tried to set up an new "placeholder" in the NewsListing snippet.
I added/changed some lines in the snippet.

[tt]
/**
* Snippet Name: NewsListing
* Short Desc: Displays News Articles and Blog Posts
* Created By: The MODx Project
* Version: 6.3.1

...

// ---------------------------------------------------
// Parameters
// ---------------------------------------------------

// added picture placeholder before summary text

$tpl = isset($tpl) ? $modx->getChunk($tpl):’
<div class="nl_summaryPost">
<h3><a href="[~[+id+]~]">[+title+]</a></h3>
<div>[+picture+]
[+summary+]</div>
<p>[+link+]</p>
<div style="text-align:right;">by <strong>[+author+]</strong> on [+date+]</div>
</div>
’;

...

// ---------------------------------------------------
// Process information for display
// ---------------------------------------------------

...

// Post-processing to clean up summaries
$summary = closeTags($summary);
$summary = str_replace($commentschunk,’’,$summary);

// added this line at the end
$picture = $resource[$x][’picture’];

...

// ---------------------------------------------------
// Set Placeholders
// ---------------------------------------------------

// Set placeholders that can be used in the Chunk

// Set placeholders for backwards compadibility and custom fields
$placeholders[’[+title+]’] = $resource[$x][’pagetitle’];
$placeholders[’[+summary+]’] = $summary;
$placeholders[’[+link+]’] = $link;
$placeholders[’[+author+]’] = $author;
$placeholders[’[+date+]’] = strftime($date, $resource[$x][$datetype]);
$placeholders[’[+picture+]’] = $picture;

[/tt]

But no picture!

I have only "basic" understanding of PHP. Maybe I’m completely wrong with this
Does anybody can help me with this? Maybe there is already a solution for this, but I couldn’t find one inside the forum, so far.

Thanks for help!

You just need to prefix "picture" with tv in the tpl

Oh MAN - I guess I need to read more precisely!!

[tt]
* Important Notes
* When in pagination mode (&paginate = 1) always call the snippet uncached in the [!NewsListing!] format
* Also, in pagination mode, make sure to use the placeholders for navigation!
* To display tv’s make sure you use the tv prefix!
* For example, if you have the template variable author you would put [+tvauthor+] in your template.

Thanks Mark anyway!

You still guess, but I am sure (j/k)

Glad you got it working.

No problem! Sorry about my brief response (I was typing on my PSP there...)

Thanks for the help bobtk and Mark! This was the solution for my post at http://modxcms.com/forums/index.php?topic=3246.new. I was originally trying to do this with DropMenu. Another gotcha was versioning of the NewsListing snippet. I just downloaded and installed MODx 0.9.1 which has version 4.4 of the snippet. I downloaded version 6.3.3 from http://modxcms.com/forums/index.php/topic,1235.0.html. Maybe I’m wrong, but it looks like 6.3.3. of the snippet was released before 0.9.1 of MODx?

Here’s the code I modified, using a TV = thumb (for thumbnail pict).

line 163:
// ORIGINAL
// $tpl = isset($tpl) ? $modx->getChunk($tpl):’
// <div class="nl_summaryPost">
// <h3><a href="[~[+id+]~]">[+title+]</a></h3>
// <div>[+summary+]</div>
// <div style="text-align:right;">by <strong>[+author+]</strong> on [+date+]</div>
// </div>

// CHANGES
$tpl = isset($tpl) ? $modx->getChunk($tpl):’
<div class="nl_summaryPost">
<a href="[~[+id+]~]">[+title+]</a>
<div>[+summary+]</div>
<div><img src="[+tvthumb+]"/><div>
</div>
’;

line 557:
// CHANGES
$thumb = $resource[$x][’thumb’];

line 590:
// CHANGES
$placeholders[’[+thumb+]’] = $thumb;

The 6.x series is much newer than the 4.4 series. It just looks that way because of how SMF keeps track of a topics createdon date and not editedon date.

I’m going to reopen this old topic instead of starting a new one because my question is somewhat related.

What I’m wondering about is the step before skiphreak got to - that is setting up the template variable and making a customized input form for [+picture+].

I’ve looked through the documentation but couldn’t find a definite answer to how you make a TV customized for the blog form. This is what I thought would work:



And then just creating a picture TV with a text input-type. The problem is that the form doesn’t output the input text form where you can fill in what Picture is supposed to be... Am I supposed to use widgets? I’m fairly new to ModX so please pardon the simplicity of this question and thank you very much in advance for the support.

Edit: Is it possible to have custom templates for the actual blog entry as well and not just the summary?

Bump... Having the same problem. Getting empty image place holders.

What I’ve done:
- Created Image TV called DittoImage with input type as Image (no other changes made to the default TV settings).
- Created a template for summaries created by Ditto. The template calls [+tvDittoImage+].

Created several test posts and assigned the TV DittoImage and uploaded an appropriate thumbnail. Saved the entry and all loads except for the image information.

Any suggestions? This is a fresh install of ModX and Ditto so everything’s current and up-to-date.

Hi,

is the DittoImage tv attached to the template of the document where the list is displayed?
If not, you have to set the param &hiddenTVs=`DittoImage ` in your dito call.
