Magento 2 : remove delete image checkbox from admin edit form

Question

I have add an image upload field in my modules edit form using-

$fieldset->addField(
 'image',
 'image',
 [
 'name' => 'image',
 'label' => __('Image'),
 'id' => 'image',
 'title' => __('Image'),
 'class' => 'required-entry',
 'required' => true,
 ]
);

While editing row it displays checkbox to delete image, I have only one image upload field and that is required also. So I want to remove this checkbox. How can I remove this checkbox?

• Manashvi Birla: a similar solution exists in magento-1.x magento.stackexchange.com/a/73870 so you can use the same for magento 2

Answer 1

As @Manashvi Suggested I tried to solve it the way it was done in Magento 1.x and it worked. I created a custom renderer for the image. and created a class in my module [Namespace]_[Module]_Block_Adminhtml_Helper_Image_Required with this content

class Required extends \Magento\Framework\Data\Form\Element\Image
{
 protected function _getDeleteCheckbox()
 {
 return '';
 }
}

Then in my form block, right above field added this lines

$fieldset->addType('required_image', 'Namespace\Module\Block\Adminhtml\Helper\Image\Required');

and defined field like this:

$fieldset->addField(
 'image',
 'required_image', [
 'name' => 'image',
 'label' => __('Image'),
 'id' => 'image',
 'title' => __('Image'),
 'class' => 'required-entry',
 'required' => true,
 ]
);

• Khushbu: I am trying to achieve the same. but i get error: Cannot declare class Required because the name is already in use. Even i change it's name to something else, still i get same error with that name. Any idea?
• Piyush: such issue occurs in case when you have declared same class more than once, please check your file path and class name
• Khushbu: but even if i change class name to any other name for e.g. RequiredImage, Still i get the same error: Cannot declare class RequiredImage because the name is already in use. (i am using magento 2.2)
• Khushbu: Ok i found the issue. Just forgot to add namespace line on top of the class file!
