Popup 

Automatic popup 

The Lizmap Web Client Automatic popup displays a table showing the columns of the attribute table in two columns Field and Value, as shown below:

Field	Value
id	1
name	A name
description	This object …
photo	:-)

You can modify the info displayed through QGIS, and also display pictures or links.

Mask or rename a column 

Предупреждение

This is working only using Lizmap or Auto popup. The QGIS popup follows the QGIS maptip.

You need to use the Layer Properties ‣ Fields tab in QGIS:

to hide a column in the popup, uncheck the corresponding WMS checkbox. The WMS column is on the right of the table. This will hide the field in QGIS Server from any WMS requests.
to rename a column, you should use the alias column. But to edit this column, add it from the tab Layer Properties ‣ Attributes Form.

Usage of media: images, documents, etc.

If you want to use some media in your popup (pictures, PDF documents…) in your popup, you must use the Media directory.

For a given feature, using a path in your field starting by media/, Lizmap will display:

the image itself for jpeg or png files
the content for txt or HTML files
a link to any other file extension

Usage of external links 

You can also use, in a field, full web links to a specific page or image:

the image referred to will be displayed, instead of the links
the web link will be displayed and clickable

Lizmap HTML popup 

Введение 

If the simple table display does not suit your needs, you can write a popup template. To do so, you should know some HTML format. See e.g.: https://www.w3schools.com/html/

Предупреждение

When you use the Lizmap HTML mode, the previous configuration to rename a field does not work anymore: you have to configure what is displayed and how through the template. Managing media is also possible, but you have to configure it as well.

Deploying 

You can edit the popup template with the button Configure in the Lizmap plugin. Clicking on it you’ll get a window with two text areas:

an area where you can type your text
a read-only area, showing a preview of your template

You can type simple text, but we suggest to write in HTML format to give proper formatting. For instance, you can add paragraphs, headings, etc.:

<h3>A Title</h3>
<p>An example of paragraph</p>

The behaviour is as follows:

if the content of the two areas is empty, a simple table will be shown in the popup (default template)
if the content is not empty, its content will be used as a template for the popup

Lizmap Web Client will replace automatically a variable, identified by the name of a field, with its content. To add the content of a column to a popup, you should use the name of the column precede by a dollar sign ($), all surrounded by curly brackets ({}).

For instance:

<h3>A Title</h3>
<p>An example of paragraph</p>
<p>A name: <b>{$name}</b></p>
<p>Description: {$description}</p>

Примечание

If you have configured an alias for a field, you have to use the alias instead of the name, between the brackets.

You can also use the values of the columns as parameters to give styling to the text. An example here, to use the colour of a bus line as a background colour:

<p style="background-color:{$color}">
<b>LINE</b> : {$ref} - {$name}
<p/>

Usage of media and external links 

You can use the media referred to in the table content, even if you use a template model. To do this, you should use the media column, taking into account the fact that Lizmap Web Client automatically replaces the relative path of the type /media/myfile.jpg with the full URL to the file, accessible through the web interface.

You can also use full URLs pointing to the pages or images on another server.

Here an example of a template handling media and an external link:

 <p style="font-size:0.8em;">A Title</p>
 <p>The name is {$name}</p>
<p>
   A sample image<br/>
   <img src="{$image_column}" style="">
 </p>

 <p><a href="{$website}" target="_blank">Web link</a></p>

 <p><img src="https://www.3liz.com/images/logo-lizmap.png"/></p>

One to many relations 

It is possible to display multiple objects (photos, documents) for each geographical feature. To do so, you have to configure both the QGIS project and the Lizmap config.

In QGIS project:

Use 2 separate layers to store the main features and the pictures. For example trees and tree_pictures. The child layer must contain a field referencing the parent layer id.
Configure aliases and field types in Layer Properties -> Fields. Use Photo for the field which will contains the relative path to pictures.
Add a relation in QGIS project properties between the main layer trees and the child layer tree_pictures in Project properties -> Relations.
Add data to the layers. You should use relative path to store the pictures path. Theses paths must refer to a project media subdirectory, for example: media/photos/feature_1_a.jpg

In Lizmap plugin:

In the Layers tab, activate popup for both layers. You can configure source of the popup if you need specific layouts
For the parent layer, activate the option Display relative children under each object (use relations)
Optionally, add the two layers in the Attribute table tab
Optionally, you can activate editing for the two layers, to allow the web users to create new features and upload pictures
Save and publish your project and Lizmap configuration

In Lizmap Web Client:

If relative children popup are defined as Automatic, this button will be visible in the feature’s popup at the top of related objects. Click it to compact all related objects in one table with search, sort and paging capabilities.

Display children in a compact way 

You can change the way children are displayed and make them look like a table. For that, you will need to adapt the HTML of your children layer and use a few classes to manipulate it.

«lizmap_merged» : You need to attribute this class to your table
lizmapPopupHeader : If you want to have a better display of your headers, you will need to put this class in the „<tr>“ who contains them
lizmapPopupHidden : This class permit you to hide some elements of your children that you want to hide when there are used as a child but you still want to see them if you display their popup as a main Popup

Here an example:

<table class="lizmap_merged">
 <tr class="lizmapPopupHeader">
     <th class="lizmapPopupHidden"><center> Idu </center></th>
     <th> <center> Type </center> </th>
     <th> <center> Surface</center> </th>
  </tr>
  <tr>
     <td class="lizmapPopupHidden"><center>[% "idu" %]</center></td>
     <td><center>[% "typezone" %]</center></td>
     <td><center>[% "surface" %]</center></td>
  </tr>
