Ajax & PHP notepad how do I...

mattd8752 · January 14, 2007

I have a rather large script which I will attach. Basically the script writes to a notepad, and everytime onkeyup() is triggered from the text area, it is saved to the database. I would also like to add a save as button. I can code this button in php myself to make it change the name of the text file in the database, however I would like to make it so that when the button is clicked in the bottom box/div (the code is hosted at http://mattdsworld.theicy.net/note/form.html ) the top section which I would place in a div (the text area) turns into a screen where the user has to put in their info. Just a few fields. Possibly just 1 (the file name). I don't need help coding it. I do need help making clicking that button replace that text area with a form, and then being able to return to the same data. (reloading back to a new dataset). I have no idea how I would do this, but I am willing to learn if someone can tell me what to learn. I will upload all files except the php since there is no need for that.

mattd8752,

I'm not sure if I understand exactly what you want, but I think what you want is to use <div> hide and show code.

Below you will find your code modified to include a "Save" button. Also, I changed the onKeyUp to onBlur,
so the data only gets sent once ( when the user is finished filling in the text area. )

When the user hits the Save button, the current <div> is hidden by a small javascript, and the <textarea> data is sent off for AJAX processing. AJAX calls fillInTheBlanks.php, which is just a simple form I found on the net. The call to the PHP script also parrots back the user data from your <textarea> from the first page, and gives the user a chance to fill in some blanks... This will sit on top of your original ( now hidden ) <textarea> <div>. You can now save your data to your database. After the user fills in the blanks ( whatever input fields you want ) and hits Submit, you can output anything you want.

Hope this is what you are looking for.

If not, let me know and I can investigate further.
