CC6 show existing image when in edit view

Question

Hi Max,

I am using the new CC6 (About time!) I have my CC view set up from the table and it shows the data I want to, I have an edit button which takes me to the inbuilt CC6 edit form, above the new image upload box I have a custom area which I am attempting to use php to display the currently saved image, or if it's empty it shows my blank.jpg file.

The code that I have adjusted from the original CC4/CF4 topic is:


<?php
if ( !empty($this->get("read_vehicle.Vehicle.image")) ) {
  echo "<img src='".JURI::root()."components/com_chronoforms5/chronoforms/uploads/newvehicle/ *dynamic-data*' />";
} else {
  echo "<img src='".JURI::root()."components/com_chronoforms5/chronoforms/uploads/newvehicle/blank.jpg' />";
}
?>

What is the correct method to fill the area "dynamic-data" so it displays the current uploaded image?

Thanks in Advance

Dave

I solved my issue after having a good think over the problem along with reading one of Max's other answers on a similar matter.

The essential information is the correct use of the variables when working inside PHP tags the following syntax is required:


$this->get("function Name.Model Name.field Name");

In the html element we can switch back to a normal var which is converted automatically on page load by CC6.


{var:function Name.Model Name.field Name}

The full code which I used to show the current image is below, this was inserted inside a custom element in the CC6 form, I can see no reason why the same won't apply to CF6 as well.


<label for"current-image">Current Image</label>
<?php
if ( !empty($this->get("read_vehicle.Vehicle.image")) ) {
  echo '<img src="/components/com_chronoforms5/chronoforms/uploads/newvehicle/{var:read_vehicle.Vehicle.image}" />';
} else {
  echo '<img src="/components/com_chronoforms5/chronoforms/uploads/newvehicle/blank.jpg" />';
}
?>

Max, Bob,

If you can see a way to improve my code I am all ears🙂
