To fix this error, you have to analyze and follow the error message to get a solution. In a recent experience with one of our client's application, we observed that a wrong SQL code was imputed in the SQL Query Box. Take a look at this sql pattern;
$query = $db->table->get['table_name'];You will see that there is an error in the use of box brackets instead of round brackets.
To fix this issue, use the correct format below;
$query = $db->table->get('table_name');In another case, a client kept getting the following error message;
A PHP Error was encountered
Severity: Notice
Message: Use of undefined constant user_array - assumed ‘web_array’
Filename: directory/filename.php
Line Number: 12By mere observing the code, you will see the constant web_array is not in the correct variable form.
To fix this we simply put an "$" symbol as a prefix to get a defined constant ($web_array).
