PHP button function call issues

[Iconate]

I have read into it, and in order to have a proper function call from a button, you need to have something of this format

 

<form action="<?=$_SERVER['PHP_SELF'];?>" method="post">

<input type="button" name="submit" value="Submit">

</form>

 

then have php at the top of your page

 

<?php

if(isset($_POST['submit'])) {

foo();

}?>

 

The only problem is, in my code, I have to cut my function short to insert the button I want. I do not know if thats the issue, but my function is not being called.

My MySQL statement works, no issue there.

 

<?php  

//all php code above, DB connections etc...

function dataInsert()          //Function trying to be called
{
mysql_query("INSERT INTO b18_3420450_cal.dates (event_id, arena, date, end_date)
VALUES ('6', '1', '2009-05-05 11:00:00', '2009-05-05 12:00:00')")
	or die(mysql_error());	
}

if(isset($_POST['book']))           // calling dataInsert if book is submitted
{
dataInsert();
}

function timeCompare($tabletime)
{


global $result;
global $q;
$available = true;

while ($row = mysql_fetch_array($result))
    {
	$qtime = substr($row['date'], 11, 16);
	if ($tabletime == $qtime)
	{
		echo "<td>TAKEN</td>";
		$available = false;
		break;
	}
    }
if ($available)
{

	echo "<td>";
	echo "AVAILABLE - ";                
	?>
	<form action="<?=$_SERVER['php_SELF'];?>" method="post">
	<input type="submit" name="book" value="   Book Now   ">
	</form>
	<?php 
	echo "</td>";
}


if (mysql_num_rows($result) != 0)
{
	mysql_data_seek($result,0);
}
}

echo "<table border='1'>";

echo "<tr>";
echo "<th>Time</th>";
echo "<th>Availablility for ". $weekday .", ". $q ."</th>";
echo "</tr>";

echo "<tr>";
echo "<td>08:00</td>";
timeCompare("08:00:00");
echo "<tr>";
...

 

Is what I did legal? Is there a way around it if its not? Because I need the timeCompare function to determine the Availability of the indicated time, if available a user could click the button to sign up for that time

Define legal.

 

Also, I don't understand what you mean by "cut my function short to insert the button I want". Please elaborate on that.

 

Thanks!
