  • To assign a unique id - you must uniquely identify this tag - have ideas how you want to do this? - Axenow
  • @Axenow must be assigned an id for each tag. <p id = "<? php $ a;?> Text </ p> It would not be bad to assign the value of the variable $ a. The value of the variable is time in ms. - Vladislav Samokhin
  • For each tag on the page? That is, you first generate the page, then click on the button and each tag gets a unique id - right? - Axenow
  • At the moment, when I click on the button, I insert it into the text in the textarea. Insert text button - inserts <p> Text </ p> - Vladislav Samokhin
  • And you can ask to add here your which, you have? Based on it, it will be easier to do what you ask for. - Axenow
