Best solution workaround for needing a mysql event on insert?


Best solution workaround for needing a mysql event on insert?

To fix this issue To address the problem of updating or deleting related entries from the event table, just create a foregin key to the programmed_delivery table.
Indeed it is not possible to manage events from a trigger, but a single "master" event could run on a regular and frequent basis (even every minute), which checks the event for something to do.

I wish this help you I didn't think there was a CSS-only solution.
For the record, I ended up injecting javascript into the page that overrides the Ext.Toolbar prototype for the insertButton() function to check for the existance of "this.tr.childNodes([0])" and default to addButton() if it didn't exist.

With these it helps Two alternate solutions would be to either use a CursorWrapper, or use the ProjectionMap of a ManagedQuery to map your uid to_id.

Needing a workaround for IE bug with SVG attribute filterUnits

Needing a workaround for IE bug with SVG attribute filterUnits

I wish did fix the issue. IE11 seems to use a stroke width of 0 when calculating the filter region - regardless of how big your stroke is, AND it doesn't seem to support specifying the filter region in userSpaceUnits (even when you tell it to). This means that the filter region for a horizontal or vertical line is zero units for the y and x dimensions respectively.
A terrible terrible but effective hack is to draw a transparent shape with the filter dimension that you want along with your horizontal or vertical lines, and set the filter on a group element grouping that shape along with your desired shape.
code :
<svg x="0px" y="0px" height="500px" width="500px" viewbox="0 0 500 500">
    <defs>
        <filter id="f1" x="-200%" y="-200%" width="400%" height="800%">
            <feOffset result="offOut" in="SourceAlpha" dx="5" dy="5" />
            <feGaussianBlur result="blurOut" in="offOut" stdDeviation="3" />
            <feComposite in="SourceGraphic" in2="blurOut" mode="normal" />
        </filter>
    </defs>
    <line x1="10" y1="205" x2="400" y2="200" 
        style="stroke:rgb(255,0,0); stroke-width:20" filter="url(#f1)" />
    <line x1="200" y1="50" x2="220" y2="300" 
        style="stroke:rgb(255,0,255);stroke-width:20" filter="url(#f1)" />

  <g filter="url(#f1)">
  <line x1="10" y1="100" x2="400" y2="100" style="stroke:rgb(255,0,0);stroke-width:20"  />
    <line x1="10" y1="100" x2="400" y2="110" stroke="red" stroke-opacity="0" />
    <g>

To fix the issue you can do I will anwser myself but if you guys have other solution I'm still interested to heard it. This solution works for me because I'm working on a new project so it don't really impact the code I already wrote.
To workaround this problem, I add a new column to my "slot_place_box" table :
code :
+----------------------+
| SLOT_PLACE_BOX       |
+----------------------+
| - id_slot_pb         | 
| - id_place_box       |
| - date               |
| - hour               |
| - slot_available     |
| - virtual_hour       | <- new field
+----------------------+
UPDATE slot_place_box SET (virtual_hour = IF(hour is NULL, '1', hour);
// Without the safe UPDATE (I use MySQL WorkBench)
 foreach($SPB_data_array as $index => $SPB_data) {
    $current_id_pb = $SPB_data['id_pb'];
    $current_date  = $SPB_data['date'];

    if (!empty($SPB_data['hour'])) {
        $current_hour = $SPB_data['hour'];
        $sql_slot_pb .= 'INSERT INTO media.slot_place_box (id_place_box, date, hour, virtual_hour) VALUES ('. $current_id_pb .', \''. $current_date .'\', \''. $current_hour .'\', \''. $current_hour .'\')
                            ON DUPLICATE KEY UPDATE id_place_box=id_place_box;
                         SET @id = (SELECT SPB.id_slot_pb FROM media.slot_place_box as SPB
                            WHERE SPB.id_place_box = '. $current_id_pb .' AND SPB.date = \''. $current_date .'\' AND SPB.hour = \''. $current_hour .'\');
                         INSERT INTO media.slot_config (id_config, id_slot_pb) VALUES (:new_config_id, @id);
                         ';
    } else {
        $sql_slot_pb .= 'INSERT INTO media.slot_place_box (id_place_box, date, hour) VALUES ('. $current_id_pb .', \''. $current_date .'\', NULL)
                            ON DUPLICATE KEY UPDATE id_place_box=id_place_box;
                         SET @id = (SELECT SPB.id_slot_pb FROM media.slot_place_box as SPB
                            WHERE SPB.id_place_box = '. $current_id_pb .' AND SPB.date = \''. $current_date .'\' AND SPB.hour IS NULL);
                         INSERT INTO media.slot_config (id_config, id_slot_pb) VALUES (:new_config_id, @id);
                         ';
    }
}
