mysqli signal to php error

✔ Recommended Answer

The real problem in the code above is that variables are not Declared. so i changed this Select statements to Declare statements.

BEGINDECLARE lastActionID INT unsigned;DECLARE lastTransferID INT unsigned;DECLARE retval INT unsigned;    START TRANSACTION;        SELECT SUM(ad.Quantity) INTO retVal FROM productin pri JOIN actiondetails ad ON ad.ID=pri.ID;        IF DualOperation = 1            THEN                IF retVal>Quantity                    THEN                        INSERT INTO Actions (EmployerID, StorehouseID, `Date`)                            VALUES (EmployerID, StoreFromID, CURDATE());                        SET lastActionID = (SELECT ID FROM Actions ORDER BY ID DESC LIMIT 1);                        INSERT INTO ProductTransfer (ID, TransferType)                            VALUES (lastActionID, 0);                        INSERT INTO ActionDetails (ID, ProductID, Quantity)                            VALUES (lastActionID, ProductID, Quantity);                        SET lastTransferID = (SELECT ID FROM ProductTransfer ORDER BY ID DESC LIMIT 1);                        INSERT INTO Actions (EmployerID, StorehouseID, `Date`) VALUES (EmployerID, StoreToID, CURDATE());                        SET lastActionID = (SELECT ID FROM Actions ORDER BY ID DESC LIMIT 1);                        INSERT INTO ProductTransfer (ID, TransferType, ParentID) VALUES (lastActionID, 1, lastTransferID);                        INSERT INTO ActionDetails (ID,ProductID, Quantity)                            VALUES (lastActionID, ProductID, Quantity);                    ELSE                        SIGNAL SQLSTATE '45000'                    SET MESSAGE_TEXT = 'Not enough materials';            END IF;        ELSE                INSERT INTO Actions (EmployerID, StorehouseID, `Date`)                    VALUES (EmployerID, StoreID, CURDATE());                SET @lastActionID = (SELECT ID FROM Actions ORDER BY ID DESC LIMIT 1);                INSERT INTO ActionDetails (ID, ProductID, Quantity)                    VALUES (lastActionID, ProductID, Quantity);                IF InOrOut = 0                    THEN                        INSERT INTO ProductIn (ID, OrganizationID) values (lastActionID, NULL);                    ELSE                        IF retVal>Quantity                            THEN                                INSERT INTO ProductOut (ID, OrganizationID) values (lastActionID, NULL);                            ELSE                                SIGNAL SQLSTATE '45000'                            SET MESSAGE_TEXT = 'Not enough materials';                    END IF;                END IF;        END IF;    COMMIT;    select true;END

The "mysqli signal to php error" error message is not specific enough to provide a clear answer. However, here are some general steps you can take to troubleshoot the issue:

  1. Check your PHP error log: The error log can provide more detailed information about the error. You can usually find the error log file location in your php.ini file or by running the phpinfo() function.

  2. Check your MySQL server error log: If the error is related to your MySQL database, then checking the error log for your MySQL server might provide more details about the error.

  3. Check your code: Look through your code to make sure you are using the correct syntax for connecting to your MySQL database using the mysqli extension. Check that you are passing the correct arguments to the mysqli functions.

  4. Test your MySQL connection: Try running a simple test script to connect to your MySQL database using the mysqli extension. If the test script works, then the issue might be with your application code.

  5. Upgrade your PHP version and/or mysqli extension: If you are running an older version of PHP or mysqli, upgrading to a newer version might resolve the issue.

  6. Seek help from online communities: If none of the above steps resolve the issue, seek help from online communities such as Stack Overflow, PHP.net forums or GitHub discussions, where experienced developers can help you diagnose and solve the issue.

PhpStorm, return value is expected to be 'A', 'object' returned

✔ Recommended Answer Has to be because object can be ANY class instance, even B etc. You can annotate the create() method with generics PHPDoc to tell that the return type will be the same as the input parameter class string. It gives more context info to the IDE. /** * @template T * * @param string $class * @return T */ private function create(string $class) : object { return new $class(); } P.S. Instead of create('B'); better use create(B::class) . This way the IDE can track the usages of that class for refactoring/search purposes etc. Source: stackoverflow.com Answered By: LazyOne Method #2 This error message suggests that your code is expecting a value of type 'A' to be returned, but instead, the code is returning an object. This error can occur in PhpStorm, or any other PHP development environment. To resolve this error, you should check the function or method that is returning the object and ensure that it is returning

Remove Unicode Zero Width Space PHP

✔ Recommended Answer This: $newBody = str_replace("​", "", $newBody); presumes the text is HTML entity encoded. This: $newBody = str_replace("\xE2\x80\x8C", "", $newBody); should work if the offending characters are not encoded, but matches the wrong character (0xe2808c). To match the same character as #8203; you need 0xe2808b: $newBody = str_replace("\xE2\x80\x8B", "", $newBody); Source: stackoverflow.com Answered By: Jef Method #2 To remove Unicode zero width space (ZWSP) from a string in PHP, you can use the str_replace() function to replace the ZWSP character with an empty string. Here's an example: php $str = "Hello​ World" ; // Contains ZWSP after "Hello" // Replace ZWSP with an empty string $str = str_replace ( "\u{200B}" , "" , $str ); echo $str ; // Outputs "Hello World" without ZWSP In this example, the str_replace() functi

Laravel file upload returns forbidden 403, file permission is 700 not 755

✔ Recommended Answer The issue you are facing could be due to incorrect file permissions for the storage folder. Here are some steps to fix the problem: SSH into your cPanel server. Change the permission of the storage folder to 755: chmod -R 755 storage/ This command will change the permission of the storage folder and all its contents to 755, which should give the web server permission to read and write to the folder. Check the ownership of the storage folder. Ensure that the owner of the folder is the same as the user running the web server (typically www-data on Apache): ls -l This command will list the files and folders in the current directory along with their ownership and permission details. Make sure that the owner of the storage folder is the same as the user running the web server. If the ownership is incorrect, you can change it using the following command: chown -R www-data:www-data storage/ This command will change the ownership of the storage folder and all its conten
