Temporarily disable foreign key constraint mysql

Date: December 3, 2018, 4:05 pm Author: Akram Hossain

Try DISABLE KEYS before SET FOREIGN_KEY_CHECKS=0; make sure to SET FOREIGN_KEY_CHECKS=1; after. [NOTE] It's not a good idea to set a foreign key constraint to 0, because if you do, your database would not ensure it is not violating referential integrity. This could lead to inaccurate, misleading, or incomplete data. You make a foreign key for a reason: because all the values in the child column shall be the same as a value in the parent column. If there are no foreign key constraints, a child row can have a value that is not in the parent row, which would lead to inaccurate data. For instance, let's say you have a website for students to login and every student must register for an account as a user. You have one table for user ids, with user id as a pri....

How to run foreach loop between 2 given dates ?

Date: September 13, 2017, 10:19 am Author: Akram Hossain

$begin = new DateTime( '2010-05-01' ); $end = new DateTime( '2010-05-10' ); $interval = DateInterval::createFromDateString('1 day'); $period = new DatePeriod($begin, $interval, $end); foreach ( $period as $dt ) echo $dt->format( "l Y-m-d H:i:s\n" ); This will output all days in the defined period between $start and $end. If you want to include the 10th, set $end to 11th. You can adjust format to your liking. See the PHP Manual for DatePeriod.

Date: February 1, 2016, 12:25 pm Author: Akram Hossain

If your generating a CSV with PHP you may have stumbled upon the same problem as me where any special character such as £ becomes ASCII in your CSV, this is because the encoding of your CSV is wrong and you will need to output your CSV in UTF8 to be able to use special ASCII characters in your document. Using my example below you can encode UTF8 your CSV file, you will notice a header with “Content-Encoding: UTF-8” and also in the “Content-Type” header you will see an extra parameter “; charset=UTF-8”. You will also notice the weird echo “xEFxBBxBF” – this is the BOM for the UTF-8 encoding, if your not sure what this is don't worry, it will not display in your document. Please Note! UTF-8 is not supported by Macinto....

Its called 'scenarios': http://www.yiiframework.com/doc-2.0/guide-structure-models.html#scenarios in model: public function rules() { return [ ['title', 'required', 'on' => 'create'] ]; } in controller: public function actionCreate() { $model = new Item(); $model->scenario = 'create'; ... } You'd better define scenario as a constant though. source : http://stackoverflow.com/questions/29449019/yii2-validate-only-create-action

Remove apostrophe in string

Date: November 3, 2015, 3:27 pm Author: Akram Hossain

Have a look at http://www.webmasterworld.com/forum88/7382.htm I believe that it will work OK if you escape the ' character thus: ' You can easily create a Javascript function to replace each instance of ' by '. str = str.replace(/'/g, "\'");

SyntaxError: expected expression, got '<'

Date: July 23, 2015, 11:40 am Author: Akram Hossain

Assumption here is that you're referencing the script incorrectly and the web server is serving a 404 html page. Make sure the js file is where you're referencing it from. for reference https://github.com/carhartl/jquery-cookie/issues/347#event-230595231
