Display image if field is not empty was created by nikotome

Good morning!

I'm new to FlexiContent and I'm finding it's an absolute great component.

I'm developing a template, and I would like to now if there is a way to find out if a field is empty. something like:

Code:

If (($this->fields['web']->display;) == NULL { whatever }

Can anyone help me on this? Thanks in advance

Hello

In short use:

// Item view (item layout)
$fvals = $item->fieldvalues[$field_id];

// in category view you may need to use $items[$i]->
$fvals = $items[$i]->fieldvalues[$field_id];

if ( !empty($fvals) ) ...

NOTE: our image/ image gallery field has a parameter for default image

In more details
the variable
...->display

exists only if you try to create the display HTML of the field, in your case it would be better to check the war field value which:
- is always available for checking
- is a lot faster that created field's HTML via ... putting in a template position or via ... getFieldDisplay()

Using the raw value of a field inside a template file

Hi,

I have added a new field named facebook, and made sure it was added to the template too. The new id for this field is 32.

Then, I have written the following code in the template file:

Code:

$field_id = 32;
$fvals = $item->fieldvalues[$field_id]; 
if ( !empty($fvals) ) { echo '<a href="' .  $this->fields['facebook']->display  . '<img src="/images/facebook_icon.png" />';

What's wrong?

I should think it should be:
$item->fields->display

Hello,

NOTE: before you can use a field you should make sure that it's display is created , by editting your template layout and adding the field in "RenderOnly" position,

then you can use it, as mention above,
NOTE the default performance setting in
- Componet params / Options / Create Field display

is to always create fields in Item view

so the above mentioned code will work in item view without adding to "Render Only" position, but not in category view

prefer to set parameter: Create Field display to Only when needed and add your field to Render only position for item layout too

I created my own item.xml and I didn't add a "renderonly" group. How would I activate that in my template? I made my own template and I was not aware of this.

Hello

1. just see the image here (edit category.xml and item.xml):

2. clear cache
3. Add you fields in the renderonly position and then use them inside the PHP code item.php
