drupal 7 中的 CSV 导出问题

Question

As i am new to Drupal 7 , i just wanted some feedback on how to debug the error in drupal 7

The work scenario will be,like this.

Once i have login into drupal 7 account i get these sub menus

Add Content

Find Content

Class Admin

Class Export

Now when i click on Class Export it will display a Grid with some data's and below the grid there is a CSV button which downloads a CSV format of the grid.

Till this its working fine and good.

Now the next step, In the top right side there is a edit view button which will help ne to edit / add the fields for the grid

Inside the edit view The page looks like this which is working fine

Now as you can see in the image on the left side there is a Fields section where one can add / remove the fields.

Next step i will be adding some new fields

When i click on ADD i will get the below screen, and i will select the Content : Class is certified

(Appears in : node : training_class)

I will do apply (this display) and then save it.

Now when i click on CSV button i am not able to get the file , the page is not responding.

So i got to know that when i add a field Content :

Class is certified (Appears in : node : training_class)

throws an error, But how to debug this issue?

How to find the issue in the drupal backend code base. How to find the root cause?

Any help appreciated.

Answer 1

A bit detailed answer:

1. Check on Reports -> Recent log messages from admin menu.

2. Try editing php.ini file and enabling error messages, so when code crashes you'll be able to see error message.

3. From your browser (network tab) check what happens when you click icon for document download. Check what is the response from the server.

4. run phpinfo() command ( https://www.php.net/manual/en/function.phpinfo.php ) and check is logging of errors enabled and what is location of error log file. Check that file... phpinfo() will also show you location of loaded php.ini file.
