call function

Anon

hey i m an newby on php

i have a site where i post, coming from a database a list of rows. i wrote a small script to update differenz items. its working, but how can i call my function.

i put it in an included file and now, for testing the script i just link to the hole file. but this means that the browser is pointed to the new file and need to come back. i m sure that its also possible just to call a function inside of the same file via mouseclick, but i cannot find it in the different php-support pages...

please help

if you submit form data, "something" (a script, ...) is loaded.

if you wish to remain on the page the click came from, while changing its content or processing data by clicking, have the script reload itself.

I use this construction:

<?
if(isset($ok))
{
// process data, do something
// this will no be interpreted unless the user has clicked the submit button named "ok"
}

// ==== form (page display) starts here ====
?>
< h t m l >
<body>
<form action=<?=$PHP_SELF ?>>
...
<input type=submit name=ok value=" Ok ">
</form>
</body>
< /h t m l >

On clicking "ok" (submit), the page is reloaded but the script can react on the values posted.

I hope that's what you wanted to know.

the problem is, that i don t want to use a form. i just have a link to click in a table where row for row the content of the databse is shown.

i want to click on a link and the function should update the specified database entry.

<a href="....function (id, pub)">click here</a>

anything like this is possible?

if you use a link, you can link to the page itself, too (as by using form action=<?=$PHP_SELF ?>):

action=delete is an example for some data passed that the script shall react upon, in this case deleting the record that is displayed in the table row.

...
<td><a href="<?=$PHP_SELF ?>?action=delete&id=<?=queryresult["id"] ?>">delete entry</a></td>
...

and in the top of the script there is:

if(isset($action))
{
if($action == 'delete')
{
$sql = "delete from x where id=$id";
... execute ...
}
}

// read in db rows
// then start html output

note this is only an example; on-click record deleting surely wouldn't be "search-engine proof" ...
