PHP before action and after action

由 陌路散爱 提交于 2019-12-25 01:47:08
问题 I would like to know how can I do something similar with beforeAction() and afterAction() from Yii. I need to have the same behavior in my PHP like those two functions from Yii and I don't know where to start from. What I really need in my case is that every time a function executes, it has to reload some parameters and after the function executes it's code, it has to set them again. The first action can be done in the constructor but the second one can only be done using a callback and this

Trouble with printf in Bison Rule

由 主宰稳场 提交于 2019-12-25 00:36:10
问题 I have tried something like this in my Bison file... ReturnS: RETURN expression {printf(";")} ...but the semicolon gets printed AFTER the next token, past this rule, instead of right after the expression.

That doesn't seem to work, as the

Apply the_title filter to post titles AND backend auto social-sharing plugin, but not nav menu

由 南楼画角 提交于 2019-12-24 15:38:26
问题 The Challenge I have been trying to write a filter that applies (prepends a string) to (a) post titles of a certain post type and (b) to that same post type WordPress admin backend for use by an auto social sharing plugin.

Comparing dates using Dynamic Action on DatePicker Oracle Apex

由 走远了吗. 提交于 2019-12-24 11:28:41
问题 I have a date picker where the user simply chooses a date then a Dynamic Action is suppose to send an alert if the user clicks tomorrow(sysdate+1). The Datepicker term is the simple layout. The Dynamic Action--> Name: Valid Date Event: Change Selection type: Item(s) Item(s): datepicker_name Condition: equal to Value: sysdate+1 When I run the program and click any day on the calendar, no alert comes up. I thought the problem was the format. The Dynamic Action sees the date as "DD/MM/YYYY"

问题 I need to know if it's possible to call the Click of a button from another one. private void myAction_Click(object sender, EventArgs e) { // int x; // ... } private void Go_Click(object sender, EventArgs e) { // call the myAction_Click button } Thanks. 回答1: You want: private void Go_Click(object sender, EventArgs e) { myAction_Click(sender, e); } But a better design is to pull the code out: private void myAction_Click(object sender, EventArgs e) { DoSomething(); } private void Go_Click(object
