Updating mysql php

Starting with PHP 5.5 the old mysql extension is deprecated, that means you’ll receive E_DEPRECATED errors as a warning but the code will continue running ok.

Starting with PHP 7.0 the extension is removed and your code won’t run at all.

The error/warning in PHP 5.5-5.6 will look like this: $link = mysql_connect('localhost', 'my_user', 'my_password'); if (!

$link) $db_selected = mysql_select_db('my_db', $link); if (!

I need assistance on how to UPDATE multiple tables with one statement. Each table has different columns except for the primary key.

query($quer2) as $noticia2) { Two problems with this, First, read the manual page again for query(); it returns a result object, not direct results.

Second, every mysql call that can throw an err needs error handling.

In postback, you can then retrieve an array of values from checking each checkbox indicating students who are present, and then update the database table in one query.

Thank you david, Aye, doing a more broad search I found this topic: viewtopic.php? Steps are just as simple as David stated and in the topic above. - Update to php 7.x - Open your file (make a backup first) - Replace the word "mysql" with "mysqli"and upload - Delete the cache/production directory Thank you! It was so easy to change the mysql to mysqli in the config file. Tried uninstalling all extensions, also back to default theme with all others deactivated - php7.0 would not work. Other open source gallery in subfolder is fine though.I looked into the documentation and read about updating multiple tables, but it seems that the example in the documentation is about updating multiple tables with the same columns. Table A id First Name Last Name Table B id Company Name Company Address How would you do a single UPDATE to populate both tables with the necessary data?
