Hello everyone in my case I want to add an image field in a custom form inside a custom module I have already the crud worked fine with the other fields like file_id,name,created_at updated_at, but I don't know how to add the field 'logo', and what files I have to change.
if anyone can help me please I will be appreciated ?
Add new column into InstallSchema.php for image
->addColumn(
'img',
\Magento\Framework\DB\Ddl\Table::TYPE_TEXT,
255,
['nullable' => true],
'Image'
)
Add Form type must be this
enctype="multipart/form-data" : No characters are encoded. This value is required when you are using forms that have a file upload control.
$form = $this->_formFactory->create(
['data' => [
'id' => 'edit_form',
'enctype' => 'multipart/form-data',
'action' => $this->getData('action'),
'method' => 'post'
]
]
);
Add field into your form
$fieldset->addField(
'img',
'image',
[
'name' => 'img',
'label' => __('Upload Image'),
'title' => __('Upload Image'),
'required' => true,
'note' => 'Allow image type: jpg, jpeg, png',
'class' => 'required-entry required-file',
]
);

$result = $uploaderFactory->save($destinationPath);
