[RESOLVED] condition display variables

music_man

In a flat file database I have 7 fields saved and separated by pipe. The last one [6] is a "Yes" or "No".

I was wondering how to make it so that the site could display all the records that has "Yes" in that record and the ones with "No" in a separated place.

Here is my code so far. It doesn't appear to distinguish.

<?php $page="classes"; include ("inc/files/header.php"); ?>

 <div id="content">
            <h3>
<?php
$userinfo1 = file("events.txt");

foreach($userinfo1 as $key1 => $val1) 
{
   //explode that data into a new array:  

   $data1[$key1] = explode("|", $val1);
}

echo 'Past events<br /><br />';

for($k = 0; $k < sizeof($userinfo1); $k++) 

{ 

if ($data1[$k][6] = "Yes") {

echo '<a name=' . $data1[$k][0] . '>';
echo 'Event: <b>' . $data1[$k][0] . '</b><br /><br />';   

echo 'Day: <b>' . $data1[$k][1] . '</b><br /><br />';
echo 'From: <b>' . $data1[$k][2] . '</b> till <b>' . $data1[$k][3] . '</b><br /><br />';
echo 'A little about the event:<br /><br />' . $data1[$k][4] . '<br />';
echo '<hr />';
}

}

echo 'Upcoming events<br /><br />';

for($k = 0; $k < sizeof($userinfo1); $k++) 

{ 

if ($data1[$k][6] = "No") {

echo '<a name=' . $data1[$k][0] . '>';
echo 'Event: <b>' . $data1[$k][0] . '</b><br /><br />';   

echo 'Day: <b>' . $data1[$k][1] . '</b><br /><br />';
echo 'From: <b>' . $data1[$k][2] . '</b> till <b>' . $data1[$k][3] . '</b><br /><br />';
echo 'A little about the event:<br /><br />' . $data1[$k][4] . '<br />';

echo '<hr />';
}
}

?>
            </h3>
        </div>
        <!-- // content -->
<?php include ("inc/files/footer.php"); ?>

Hi,

Did not look at the logic of the code -I am sure it could be more efficient- but the comparison should have double = signs:

if ($data1[$k][6] == "Yes") {

Instead of the == "No", you could use else { which will make sure all records are displayed, also if you forget to place a no, or if you have typos.

I have tried that with double quotes and it does not work. The reason why I had the code repeat and with "No" is because I would like a heading above the whole segment of No's rather than "Past events" on every "no" entry.

ok,

will get back to you in 10 minutes. I'll have a look

Hm.. phpbuilder server went down.. Anyway.. hope this works for you:


<?php
$userinfo1 = file("events.txt");
$datay = array();
$datan = array();

foreach($userinfo1 as $key1 => $val1) 
  {
   //explode that data into a new array:  

   $datat = explode("|", $val1);

   if(trim($datat[6]) == "Yes")
     {
     $datay[] = $datat;  // all YES records
     }
   else
     {
     $datan[] = $datat;  // All others
     }
  }

echo 'Past events<br /><br />';

foreach($datay as $key=>$value)
  {
  echo '<a name=' . $value[0] . '>';
  echo 'Event: <b>' . $value[0] . '</b><br /><br />';   

  echo 'Day: <b>' . $value[1] . '</b><br /><br />';
  echo 'From: <b>' . $value[2] . '</b> till <b>' . $value[3] . '</b><br /><br />';
  echo 'A little about the event:<br /><br />' . $value[4] . '<br />';
  echo '<hr />';
  }

echo 'Upcoming events<br /><br />';

foreach($datan as $key=>$value)
  {
  echo '<a name=' . $value[0] . '>';
  echo 'Event: <b>' . $value[0] . '</b><br /><br />';   

  echo 'Day: <b>' . $value[1] . '</b><br /><br />';
  echo 'From: <b>' . $value[2] . '</b> till <b>' . $value[3] . '</b><br /><br />';
  echo 'A little about the event:<br /><br />' . $value[4] . '<br />';
  echo '<hr />';
  }
?>

It does thank you!

Could you please tell me the variable that says whether it is a past event or not please? The reason is that I can't find it to make Past events display a "No past events" or not display the text if there are no entries.
