I have a php page that displays in an html table all the rows from a database table.
I would like to add the option to delete a given row in my php page.
Here is an image to illustrate, I have already the table, just need another column with the respetive delte row option.
In other question, @Ray_Paseur helped me to organize the contents but he said something about the delete option that I want you to consider:
In order to delete a row or a set of rows from the data base table,
you will need to make a POST-method request to a script that runs a
DELETE query. The common design pattern for something like what
you've shown here goes this way (sorry there is not a simple answer).
The "X delete entry" column contains a link to a delete script.
The link looks like this URL:
In that URL, the $id variable is the key of the data base row to be deleted.
When the script is started via a click on the link, it is started via a GET request.
The variable $_GET['q'] contains the id. The script will use the id to SELECT the
row and display some of its information, perhaps the company name, along with the
question, "Do you really want to delete?" Below the question will be an HTML
submit control that makes a POST method request to the deletion script, passing
the id. The DELETE query will have a WHERE clause that identifies the target
row and a LIMIT clause that sets the query to remove only one row.
The nature of the "delete" option is a little complicated. You need to understand
the HTTP protocols to know why a POST request is required, but an example might help.
Imagine if you had a delete script that used the GET method request. In a GET request,
the request information is transmitted in the URL variable. If a script made a DELETE
query on the basis of the URL variable alone, there would be a risk, to say the least.
Now imagine what will happen when Google visits your page and tries to index all of
the links. Poof! All rows are gone.
I am sure that he is right about this, but for example in a CMS like wordpress, there is a delete option for posts for instance, it's something silimar that I need.
Could you give me some hints on how to acomlish this delete option?
Thanks a lot.
