Hey gang,
I've got a complex algorithm that I'm trying to work out. I'm trying
to store and retrieve a set of switches in a decimal representation
of a binary number. I have four checkboxes, call them A, B, C, and D.
They can be represented by a (decimal) number from 0 to 15 in binary
(0000 to 1111). I need to be able to store and retrieve this set of
data.
I've got the script to store it, and I thought I had the script to
retrieve the data, but I can't seem to get the checkboxes to actually
be checked (or not) depending on the value in the database.
I don't like dealing with the data this way, but the program I'm
interacting with requires it.
The script below is used to handle a number of data elements on the
page.
$pagevars is an array of the variables on the page, and the table
they are located in.
set_val(a,b) puts the values in array a into the variables listed in
array b.
form_element(a,b) is a function that returns a form element of type a
(CB, TB) with the variable a. So form_element("CB","var") returns the
following:
<INPUT TYPE="CHECKBOX" NAME="var" />
If the value is 1 or on, CHECKED will be added.
Here's the script:
--- START CORE.PHP ---
<?php
include("../functions.inc");
include("menu.html");
$pagevars=array("statistics"=>array("StatFlags","StatFiles","StatMail","STF_Hours","STM_Hours"));
if (isset($_POST['submit'])) {
$stat=$_POST['stat'];
for ($i=0;$i<4;$i++) {
$t[$i]=isset($stat[$i])?"1":"0";
}
$stat=implode("",$t);
$StatFlags=bindec($stat);
$_POST['StatFlags']=$StatFlags;
unset($_POST['stat']);
if (!set_val($_POST,$pagevars)) {
echo "data not written to database. Contact system administrator";
}
}
$page_var_vals=get_vars($pagevars);
if (is_array($page_var_vals)) {
extract($page_var_vals);
}
echo "StatFlags:$StatFlags<BR>";
$stat=preg_split('//', str_pad(decbin($StatFlags), 4, "0",
STR_PAD_LEFT), -1, PREG_SPLIT_NO_EMPTY);
for ($i=0;$i<4;$i++) {
$stat[$i]=($stat[$i]==1)?"on":"";
}
debug($stat);
?>
<H1>Statistics</H1>
<FORM METHOD="POST" ACTION="<?php echo $_SERVER['PHP_SELF'];
?>">
<p><?php form_element("CB","stat[0]"); ?>Save statistics to a
file periodically
Every <?php form_element("TB","STF_Hours"); ?>hours</p>
<p>Save in: <?php form_element("TB","StatFiles"); ?></p>
<p><?php form_element("CB","stat[1]"); ?>Email statistics
periodically
Every <?php form_element("TB","STM_Hours"); ?>hours</p>
<p>Send to: <?php form_element("TB","StatMail"); ?></p>
<p><?php form_element("CB","stat[2]"); ?>Automatically open
the statistics window at startup</p>
<p><?php form_element("CB","stat[3]"); ?>Collect statistics
about mail sent by local users</p>
<p>System Messages</p>
<p>System reporting level:
<SELECT NAME="">
<option value="0">
0 - No messages
</option>
<option value="1">
1 - Urgent messages
</option>
<option value="2">
2 - Significant messages
</option>
<option value="3">
3 - Normal messages
</option>
<option value="4">
4 - Informational messages
</option>
<option value="5">
5 - Debugging messages
</option>
</SELECT></p>
<p>Number of messages to store: <?php form_element("TB","");
?></p>
<p><?php form_element("CB",""); ?> Automatically open the
system messages window on startup</p>
<INPUT TYPE="SUBMIT" NAME="submit" VALUE="Save" />
<INPUT TYPE="Reset" VALUE="Cancel" />
</form>
</body>
</html>
--- END CORE.PHP ---
