image url

[Frank Vèssia]

I'm noticing a strange behavior of the image->url property.

I call a php file from jquery that display an image and a message so i have to put my php file outside the /site/ dir, but when i call  $image->url it returns /my-external-dir/site/assets/file/etc...

<?
require_once('../index.php');
$messages=$wire->pages->find("template=wallmessage,limit=20,sort=-created");
foreach ($messages as $message){
$username = $message->parent->parent->name;
$profilephoto = $message->parent->parent->profilephoto->eq(0)->size(60,60);
echo "<p><img src='http://{$_SERVER['HTTP_HOST']}{$profilephoto->url}' /><div><a href='/profilo/{$username}'>{$username}</a></div><div>{$message->wallmessage}</div></p>";
}
?>

Don't know why it is so. But Ryan certainly could tell you what's up with this.

You could alternatively put the file in the root, this would work. Or if you got it in a folder in the root you could filter out the additional path segment. Simple as that:

$path = str_replace('/myfolder','',$img->url);

[Frank Vèssia]

i can surely use str_replace but it's not a nice solution, i will wait Ryan 

[ryan]

Sevarf2, I don't think I understand. Can you post what the expected output is in addition to the output you are getting? Or if you have a live link I can click on to see what it's doing, even better.

[Frank Vèssia]

The correct path must be /site/assets/etc... but i have /process/site/assets/etc..  /process/ is the external folder where is my php file called by jquery.

[ryan]

Is your site running off a subdirectory called /process/ ?

[Frank Vèssia]

Not, my site is running in root but i put this file outside because i tried (using jquery) to call it from inside some pw folders but i always get "file not found".

[ryan]

I see what you mean. I can duplicate here too. I will work on this and post a fix shortly.

[Frank Vèssia]

thank you 

[ryan]

Okay I think I've got it fixed. You'll want to grab the latest P21 commit, or if you prefer just the /index.php file from it. Thanks for finding this issue.

[Frank Vèssia]

Thank you so much. You are always fast  ;D

[Soma]

Thanks Ryan for this fix, I grabed it and still not working for me.

Bootstraping from a subdirectory outside of PW dirs, it includes the subdirectory in the image url.

[ryan]

Soma, can you try this test:

1. Create a subdirectory off of your PW installation directory, i.e. /test/

2. Put this file in there:

/test/test.php

<?php
include("../index.php"); 
echo $wire->pages->get("/some/page/")->url; 

If your site is installed at root, it should say:

/some/page/

If your site is installed in a subdir, it should say:

/subdir/some/page/

Are you getting something different? If so, what's the server environment? If you have phpinfo output that you want to PM me a URL to, that's all I would need to see.

Also, double check that your /index.php is the latest version from yesterday (which is where this change was made). Very often when people (at least me) update their PW install, they just replace the /wire/ dir and not the /index.php, but this is one case where you'd need to replace the /index.php in order for it to work.

Thanks,

Ryan

Ok I got it on local server.  Normal install, latest version (with latest inde.php)

I create a strap.php in myfolder like: http://pw2.ch/myfolder/strap.php

Code in strap.php:

<?php
include('../index.php');
$p = $wire->pages->get("/about/")->children->first();

foreach($p->images as $img){
	echo "<img src='{$img->url}'/>";
}
?>

Output code is:

<img src='/myfolder/site/assets/files/1002/p1000832.jpg'/><img src='/myfolder/site/assets/files/1002/p1000840.jpg'/><img src='/myfolder/site/assets/files/1002/p1000835.jpg'/><img src='/myfolder/site/assets/files/1002/p1000176.jpg'/><img src='/myfolder/site/assets/files/1002/p1000183.jpg'/><img src='/myfolder/site/assets/files/1002/p1000184.jpg'/><img src='/myfolder/site/assets/files/1002/p1000185.jpg'/><img src='/myfolder/site/assets/files/1002/p1000186.jpg'/><img 

I sent you the phpinfo in a PM.

Thanks

[ryan]

Thanks for sending that. Can you try this in your strap.php and tell me what the output is?

<?php
include("../index.php"); 
echo "<pre>";
echo $_SERVER['SCRIPT_FILENAME'] . "\n";
echo __FILE__ . "\n";

Here is the output on mine for instance (two of the same lines):

/Applications/MAMP/htdocs/skyuser/test/index.php
/Applications/MAMP/htdocs/skyuser/test/index.php

I'm guessing yours are different and we may have to use realpath(). So if they are different, try this and let me know if that does it?

<?php
include("../index.php"); 
echo "<pre>";
echo realpath($_SERVER['SCRIPT_FILENAME']) . "\n";
echo realpath(__FILE__) . "\n";

Thanks for your help testing this.

[Soma]

yes my output is:

/Applications/XAMPP/htdocs/pw2.ch/myfolder/strap.php
/Applications/XAMPP/xamppfiles/htdocs/pw2.ch/myfolder/strap.php

realpath is:

/Applications/XAMPP/xamppfiles/htdocs/pw2.ch/myfolder/strap.php
/Applications/XAMPP/xamppfiles/htdocs/pw2.ch/myfolder/strap.php

already seen (i'm fast )

[ryan]

I just updated my original message, wondering if realpath() fixes it. Not sure it'll tell you my message was updated, so you may have to click back to page 1.

[ryan]

Okay cool so it looks like realpath fixes it. I'll make the update and commit it. Thanks!

[ryan]

Soma I was wondering if you could try out this /index.php file attached and let me know if it fixes it on your end? Since I don't have an example like yours to test from I just wanted to double check before committing.

Thanks,

Ryan

index.php.txt

[Soma]

Ok, just tested and works great. Images show up

[ryan]

Great! thanks for testing, I will commit.

[Soma]

Damn, we're fast. Gotta love social coding...

Hi all! I didn't know wether to do a new post or not, because it is closely related to the above.

I've been using ProcessWire 2.2 boostrapped into Codeigniter quite succesfully, until this. I am using PW as the backend and CI as the router and front end. So PW is inside the /pw/ directory in the root. In this case I am calling some PW code directly inside a CI view. I am requesting some images from an image field and the url returned is incomplete. The rest of the fields return ok.

When using image_field->url, I get "/site/assets/files/1110/" without the image name or the extension. Then I prefixed the real base url to get the correct beginning (http://www.sitename.com). After that, I tried to call the image name and ext manually with $banner->image->name and$banner->image->ext but they return nothing. Exploring the $banner variable with var_dump i found the name under "basename" but not the extension. Also, maybe worth noting: I see a lot of "protected" strings inside the var_dump (don't know if that's normal).

I know that there's some complexity in what I'm doing but I think there's something weird o I'm doing something wrong. Or maybe I am messing with something, right?

This is the full call. Note that $pw_url adds the parent's path to where PW is nested (http://www.sitename.com).

$banners_destacados = wire('pages')->get('/home/destacados/')->children('limit=3');
foreach ($banners_destacados as $banner) {
 echo  "<div class='entrada'>".
	"<h3><a href='{$banner->pastilla_link}'>{$banner->title}</a></h3>".
	"<a class='img' href='{$banner->url}'><img src='{$banner->pastilla_imagen->url}' alt='{$banner->title}' /></a>".
	"<p class='description'>{$banner->pastilla_descripcion}</p>".
   "</div>";
 print($banner->pastilla_imagen->name);
}

What can I do?

[Pete]

I think it's possible that you may not have limited the image field to only have one entry (or it might apply wither way) but try: image_field->first()->url

[ryan]

When using image_field->url, I get "/site/assets/files/1110/" without the image name or the extension.

I agree with Pete. This sounds like you are accessing type 'Pageimages' rather than type 'Pageimage' (singular). Since you are bootstrapping ProcessWire, output formatting is going to be off. One of the side effects of that is that all image fields are treated the same (as arrays of images) rather than single images. Since you are using ProcessWire's data for output in this case, I suggest adding a single call to this before you retrieve any pages from PW:

wire('pages')->setOutputFormatting(true); 

That will turn it on for all anything returned from the $pages API var.

Or you can do it for just one page, like your banner $page:

$banner->setOutputFormatting(true); 

Turning outputFormatting on will ensure you get the correct behavior for output. And if your image field is set to hold max 1 image, then it'll also ensure you only get that when accessing $banner->pastilla_imagen.
