Child page image

Recommended Posts

Hi. I am new in process wire. 

I want to show child page image  in the list of child pages as a thumbnail  . ( like title and summary )

I tried this 

<img src='{$child->image_top->url}'>

it works but i want to show ( 300x300 px ) 

I am adding the code below. 

My image field name is : image_top

<?php 

// Output navigation for any children below the bodycopy.
// This navigation cycles through the page's children and prints
// a link and summary: 

if($page->numChildren) {

echo "<ul class='nav'>";

foreach($page->children as $child) {
echo "<li> <img src='{$child->image_top->url}'> <p><a href='{$child->url}'>{$child->title}</a><br /><span class='summary'>{$child->summary}</span></p></li>";}

echo "</ul>";
}
?>

// without testing, but you can get the idea here

foreach ($page->children as $child) {

$image = $child->image_top;

$thumb = $image->size(300,300);

echo "<li>";

echo "<img src='{$thumb->url}'>";

echo "<p>";

echo "<a href='{$child->url}'>";

echo $child->title;

echo "</a>";

echo "<br />";

echo "<span class='summary'>";

echo $child->summary;

echo "</span>"

echo "</p>"

echo "</li>";

}

Thank you for your message, it was inspiration for me, when there is no image it gave error and i added if ..

i did some thing like this and it works fine.....  just can you check if its good?

if($page->numChildren) {

echo "<ul class='nav'>";

foreach($page->children as $child) {
					
if ($child->image_top) {
    $image = $child->image_top;
    $thumb = $image->size(200,200);

echo "<li> <a href='{$child->url}'><img src='{$thumb->url}'></a>  <p><a href='{$child->url}'>{$child->title}</a><br /><span class='summary'>{$child->summary}</span></p></li>"; 
					}}

					echo "</ul>";
				}

You could set the image field to be required, that way you're sure there's an image. However, checking it will be a good practise.

      BETA: SplashAndGrab

      This module attaches a search input to selected image fields that lets you search and download images from Unsplash.
      (Unsplash is a stock photo service where you can download images for free and use as you wish. No strings attached.)   
      You can search by string, colors, orientation/crop and order by relevance or time published
      I find Unsplash useful both for placeholder images when building sites but also as a time saver for editors if they don’t have any images at hand, just search, download and publish.

      Thanks to @apeisa for building the  FlickrInputField Module and @Robin S for AddImageUrls,  took a lot ideas and code from those modules.

      We have created a module to create BlurHash strings for images while uploading in ProcessWire. This blurry images will be saved in the database because they are very small (20-30 characters) and can be used for Data-URL's  as placeholders for image-lazy loading.

      E.g. where we use this in production:

      Hello dear PW gurus.

      I have stumbled over a strange error that i all of sudden got when trying to upload an image to a images field on a page.
      There where images allready stored in the field that i wanted to keep, but during the upload the error apear and after that all images are gone from the field and i can´t upload any, i just get the error every time.
      I am running ProcessWire 3.0.153 dev.
      Update:
      After looking in the assets folder i find the folder for the page and the image files seems to be there including the ones i tried to upload when the error occured.
      But they don´t show up in the images field in the page editor.
       
      The error reported:
       
      SQLSTATE[01000]: Warning: 1265 Data truncated for column 'ratio' at row 1 And here is a screenshot of the event:

      The TracyDebugger Error reporting:

      I hope you fine folks could point me in a direction.
      But it seems our old pal set_time_limit() is back.

      Hi all
      Continuing my first project where I am creating and manipulating stuff from the frontend. Till now I've always added things like images from the backend, but in this project I need to add and move images from a frontend control. This is a photo album where images are stored in albums, each album being a page containing a Pageimages array in the usual way. So what I want to know is how do I move an image from one album (page) to another in the frontend? I just need some guidance on how to approach this.  I suppose I need to do a copy and delete - but how do I copy an image or images from one page to another? What function should I use to create a new image on an existing page? I include a code snippet from the server side of my delete image request and it works fine. I'd like to implement something similar for a move and upload new image request. 
      Many thanks for any help. Paul 
      <?php namespace ProcessWire; // sanitize inputs as 1-line text $action = $sanitizer->text($input->post('action')); $instr = $sanitizer->text($input->post('input')); $sel = $input->post('selected'); // Expect JSON for image selected image list $selected = json_decode($sel); $nosel = count($selected); $response = array(); // for building JSON response switch($action) { // delete selected images case 'delete': $out = "<p>Deleted $nosel image(s)</p>"; foreach($selected as $item){ $album = $pages->get($item->album); $album->of(false); $out .= "<p>Image {$item->file} from album {$album->title}</p>"; $album->images->delete($item->file); $album->of(true); } $out .= saveUpdatedAlbums($pages, $selected); // add the response message for the delete $response['message'] = $out; break; ...... // save any album that had an image deleted function saveUpdatedAlbums($pages, $selected) { $cur = ''; $out = ''; foreach($selected as $item){ $album = $pages->get($item->album); if($album->id != $cur) { $album->of(false); $album->save('images'); $album->of(true); $cur = $album->id; $out .= "<p>Updated album {$pages->get($cur)->title}</p>"; } } return $out; }

      Inspired by a recent question.
      Image Crop Ratios
      Allows preset aspect ratios to be defined per image field for the ProcessWire image crop tool.
      The module adds a select dropdown to the crop tool. Choose an aspect ratio and the crop area will be fixed to that ratio.
      Screencast

      Installation
      Install the Image Crop Ratios module.
      Configuration
      Default aspect ratios for all image fields can be defined in the module config. Aspect ratios for specific image fields can be defined on the Input tab of the field settings. You can override the ratio settings in template context if needed. Insert a hyphen as the first item in the ratio settings unless you want to force a ratio to be applied to the crop tool. The hyphen represents a blank option that allows a free crop area to be drawn. Usage
      Click the "Crop" link on the details view of an image thumbnail. Click the "Crop" icon at the top of the editor window. Choose an option from the "Ratio" select dropdown.
