Currently images are posted with the image title as the alt= tag, and the image description absent entirely. I'd like to make it so the title is posted as the title=tag, and the image's description posted as the alt= tag. This is fairly normal SEO stuff AFAIK.

I've taken a look at the PhotoQPhoto.php file, and the relvent line looks to be #169, but I'm a noob to PHP and I don't know how to correctly edit this line.

Also a secondary request, is there a way to get the image links wrapped in the wordpress code for captions?

did you have a look at PhotoQ's freeform option? if not grep for "freeform" here: http://www.whoismanu.com/photoq-wordpress-photoblog-plugin/

you can do all of what you intend to do directly from the photoq settings in the wordpress admin section without diving into any php code.

Thank you, I managed to skip completely over that part.

I cant get the code to paste properly, what the hell kind of forum calls itself "bbpress" but doesn't accept bbc markup?

You can also put code in between backtick ( ` ) characters.

I've run into another small issue. PHP code in the freeform section is not being executed for new posts, only when I make changes to the freeform code that causes the plugin to rebuild all posts.
And yes, I have php exec plugins for posts, two actually (tried one, then the other as I assumed at first they were the problem)

i never tried to put php code into posts that were posted with photoq. so it is well possible that it doesn't work.

could you post what you put into the freeform option? could you also tell me what plugins you use to execute it? so i can try and see whether this can be made to work at least for a future version.

thanks.

Your forum really doesn't like me posting code, so heres a pastebin link:
http://pastebin.com/m687332e8

PHP plugins are "Exec-PHP" and "PHP Execution". I prefer using the later over the former, but they both exhibit the same behavior. Again, your plugin works with them, so long as the code is executed by the control panel (when it rebuilds ALL posts). It just doesn't work for individual posts (manually posted, or queued).

Thank you.
I've taken to adding and removing a line break twice a day to force a global rebuild to fix the problem.
Doesn't really bother me much (I'd like to not have to do that...) but I'm sure my host doesn't like the massive CPU hit when I do that.

Just thought I'd make an update. It is now working correctly with manual posts, i.e "Post top of queue". It is NOT yet working with the auto/cron posts.

thanks. so what did you change to make it work?

The only change I made was the 2.9 update. The auto/cron post still isn't working, don't know what the technical difference is between how those posts work.

Also, I'v run into a small bug with image names, do you want me to open a new thread for it?

sure, always good to open a new thread for a new problem. thanks.

Hey, just wondering if this issue has come up again? I have followed the same steps as chaosratt describes above and got the same results.

I am able to use the PHP Execution plugin to pass the_permalink in the freeform field, which allows me to make the image a link to the post. Here is the contents of my freeform field: :
<a href="<?php the_permalink()?>" title="[title]"> <img width="[imgWidth|thumbnail]" height="[imgHeight|thumbnail]" alt="[title]" src="[imgUrl|thumbnail]" class="photoQexcerpt photoQLinkImg" /> </a>

This works beautifully and so my category archives can be a page of clickable thumbnails. However, when I post through a cronjob, I get this:

& lt;a href="” title=”Characters bw 057″& gt; <img width="120" height="186" class="photoQexcerpt photoQLinkImg" src="http://www.adammurphy.com/wp-content/thumbnail/2010_03/characters_bw_057.jpg" alt="Characters bw 057">
(I added a space to & lt; so it would show up on this board)

That first bit should be:
<a href="http://www.adammurphy.com/2010/03/31/characters-bw-057/" title=”Characters bw 057″>

So it's converting & lt; to < etc, there's this weird thing with "” as well as not executing the php.

A few uneducated guesses: PHP Execution plugin requires administrator permissions to run PHP code. Does the cronjob run with admin permissions? But if that was it, then why is it mangling the <? Another option: the_permalink only works in the loop. Is the cronjob somehow working outside the loop so there is no data in this variable? Forgive me if these are nonsense - I have a minimal understanding of wordpress internal workings.

You can see this in action at http://www.adammurphy.com/category/gallery/street-sketches/ I have left today's (30/03/10) post as the cronjob posted it. If I just update the post it rebuilds and fixes all of this, but that does slightly defeat the purpose of the whole cronjob thing.

Any thoughts greatly appreciated.

Thanks again for a fantastic plugin!

Adam.

hi adam,

hmm, i don't think it "came up" again. i rather think it has never been fixed :-(

thanks for the detailed description of the problem, i guess this allows me to make a few tests with php-exec and see where the problem is. probably some stuff doesn't get properly loaded when the cronjob file runs (i.e., the wordpress loading process is in this case not 100% indentical to when the index.php file is run).

unfortunately, i think that i won't be back with an answer during the next two weeks since i will be traveling. will try to look at this as soon as i can, though. thanks for understanding.

adam,

finally had the time to look into this. i think i found what the problem is. you were actually right with your guess regarding permissions. if the cronjob runs it doesn't have admin permissions. as a consequence wordpress does for security reasons not allow unfiltered html and it adds some filters (called kses) to remove any non html stuff such as the php call to the_permalink.

i found a way around it by manually turning off the filter in question for cronjobs. you need to add the following line

kses_remove_filters();

after

require_once('wp-load.php');

in the wimpq-cronpost.php file.

if you do this the kses filters do not get executed when the cronjob runs. security-wise you should still be fine since this change only affects cronjob execution. kses will still run on any user generated content such as comments.

Yes!

It works!

Thank you so much.

And yeah, considering you are providing a totally awesome plugin and really indepth support on all sorts of little niggly issues, completely for free, whenever you can get to this stuff its greatly appreciated. Hope you had good travels!

Cheers!

Adam.
