Hi All,
I am trying to create a page were users can edit their post.
-Select subbmitted data from the database using post id, and display this information so that users can Edit.
-And finally i want to update the data and continue to the preview page, where users can preview their post.
Can someone please help me with this?
I can show you the code that i have so far.
I also have error validation which is making things more difficult.
What part are you having problems with?
give me link to this?
My apologies, my code is a bit messy. I have only been programming for about a year.
So basically what I am trying o do is allow users to edit their post.
Below is the code that I am working on for the Edit page.
First I am selecting the data from mysql database based on adid and user_email.Then I want to display this information on the edit page and allow users to make any additional changes.
After I have selected the data and display it which is working correctly I want to run the error validation for what the users post and finally i want to UPDATE the data in my database.
I AM HAVING PROBLEMS WITH THE ERROR VALIDATION, when i press submit the data gets updated but the Error validation code is not functioning correctly.
Please let me know if anyone could help me out. Again, i am new to programming but I am learning fast.
