Add info from a table to an existing HTML page.
Posted on 2001-06-16
I have a nationally approved basic boating safety course at http://boatsafe.com. I want to be able to have new students select the state in which they boat and save that as a variable.
Once I have the variable I want to query a table that has state specific information. For example lifejacket wearing requirements. Then when the student gets to the existing page which has the federal regulations dealing with lifejackets, I want to use PHP to insert the information for the students state that may be different than federal requirements.
Is this possible? Any ideas or assitance would be appreciated.
Thanks, Capt Matt

pass the state value as a HTTP_POST value.
$query= "select * form state_table where state='".$HTTP_POST["state
"Then when the student gets to the existing page which has the federal regulations
dealing with lifejackets, I want to use PHP to insert the information for the students state that may
be different than federal requirements."
cannot understand this part.. please clarify it with a detailed example.

Well.. in the form that the new user fill in, there is a state field? probably a SELECT ..
So.. you could do like this:
signup.htm file:
<HTML>
<BODY>
<FORM ACTION="signup.php" METHOD="post">
<SELECT name="lifejacket">
<OPTION VALUE="FL">Florida</OPTION
<OPTION VALUE="CA">California</OPT
...
</SELECT>
<BR>
<INPUT TYPE="submit" VALUE="Signup!">
</FORM>
</BODY>
</HTML>
signup.php file:
<?
// Query the table with the lifejacket requirement table
$link = mysql_connect($SQLHost, $SQLUser, $SQLPassword) OR DIE ("Unable To Connect To Database");
mysql_select_db($SQLDataba
$sql = "SELECT * FROM tbl_lifejacket WHERE state='$state'";
$result = mysql_query($sql);
if (mysql_num_rows($result) > 0) {
while ($row = mysql_fetch_array($result)
$lifejacket_requirement = $row[your_field];
} // end while
} // end if
mysql_close($link);
// if $lifejacket_requirement isn't empty,
// meaning that there IS some specific REQUIREMENT,
// then print it, else, do nothing
if (!empty($lifejacket_requir
print "$lifejacket_requirement";
} // end if
// print the rest of your page here..
?>

signup.htm file:

<FORM ACTION="signup.php" METHOD="post">
<SELECT name="lifejacket">
<OPTION VALUE="FL">Florida</OPTION

...
</SELECT>
<BR>
<INPUT TYPE="submit" VALUE="Signup!">
</FORM>
</BODY>

$link = mysql_connect($SQLHost, $SQLUser, $SQLPassword) OR DIE ("Unable To Connect To Database");
mysql_select_db($SQLDataba
$sql = "SELECT * FROM tbl_lifejacket WHERE state='$state'";
$result = mysql_query($sql);
if (mysql_num_rows($result) > 0) {
while ($row = mysql_fetch_array($result)
$lifejacket_requirement = $row[your_field];
} // end while
} // end if
mysql_close($link);
// if $lifejacket_requirement isn't empty,
// meaning that there IS some specific REQUIREMENT,
// then print it, else, do nothing
if (!empty($lifejacket_requir
print "$lifejacket_requirement";
} // end if
// print the rest of your page here..
?>
instead of using $state, your could use HTTP_POST_VARS["state"] if you used method="post" in your <FORM> tag..
but if you used the method="get" you would have to use HTTP_GET_VARS["state"]
using $state should work fine with both method ;-)

btw, you can use the coded provided for signup.php in any php file where you want to use the lifejacket regulation..
and the query I provided.. is only if you have the state of your student..
so if you use the above code in another place than the signup page.. you would have to modify the query like:
$sql = "SELECT * FROM tbl_lifejacket WHERE state='$state' AND user_id='$user_id'";
where user_id field is the unique ID field in the table and $user_id is that ID for the current user..
