phpmyadmin throws a 404 on opening
Use this command sudo nano /etc/apache2/apache2.conf to open the file using nano then add the following line:
Include /etc/phpmyadmin/apache.conf
Save and close. Then restart the server. This should work.
Array.prototype.map() expects a return value from arrow function.eslint
Solution:
Change {} braces to ()
Change your code from
{programsData.map((program) => {
<div className=”category”>
{program.image}
</div>
})}
To
{programsData.map((program) => (
<div className=”category”>
{program.image}
</div>
))}
UI Component Listing And Not registered handle in Magento2
If you face below error in your Magento 2 custom module.
Not registered handle [namespace]_[module]_team_index_data_source
There is one reason for above error is that you are missing di.xml file from [namespace]_[module]/etc/ folder
Copy the following code into di.xml file and place it in root of the etc folder of your module. Don’t forget to change the namespace and module name according to your module in the code.
<type name="Magento\Framework\View\Element\UiComponent\DataProvider\CollectionFactory">
<arguments>
<argument name="collections" xsi:type="array">
...
<item name="[namespace]_[module]_team_index_data_source" xsi:type="string">[Namespace]\[Module]\Model\ResourceModel\Team\Collection</item>
...
</argument>
</arguments>
</type>
Magento2 InstallSchema.php does not create the table specified
DB schema command would not run again if it has been already executed so you need to remove database entry for your module in setup_module table.
Removing the record from setup_module with module = ‘MyVendor_Helpdesk’ should make it run again.
Keeping writing the good code 🙂
Points to keep in mind while developing custom form in Magento 2 module on admin end.
Two things keep in mind
1) Form action could be defined as
<?php echo $this->getUrl("pilot_smile/options/save"); ?>;
2) Do not forget to add form_key else you would be going to waste your several hours on finding the dashboard redirection issue on form submission.
<input name="form_key" type="hidden" value="<?php echo $block->getFormKey()?>" />;
Argument 1 passed to App\Service\FileUploader::upload() must be an instance – symfony 4
If you face “Argument 1 passed to App\Service\FileUploader::upload() must be an instance of Symfony\Component\HttpFoundation\File\UploadedFile, string given, ” this error while playing with files in Symfony 4. Then you need to change your file field in controller as. Change your code from
$file = $task->getTaskLogo();
$file= $form['task_logo']->getData();
Where task_logo is the name of the file field of your form.
