how to associate column record with table header? - php

Question

I have a mysql table, one of its columns called parking space has a number in it. However, for some records the 'parking space'-column is empty. Now, I want to call just this column in a page table where the column heads are numbered from 1 - 200 (first column: 1; second column: 2;....) So, if there is the value '12' in the 'parking space'-column, then this shall show up in column '12' and so on, and if there is no entry for a number then the column in the page table shall be left empty. How can I associate the numbers in 'parking space' with that page table?
...
<?php
$pagetable=array('1','2','3','4','5','6');//...until 200
foreach($pagetable as $value){
?>
<table border="1px" cellspacing="1" cellpadding="1">
<tr>
<th>
<?php echo $value ?>
</th>
</tr>
<?php
}
include("dbinfo.inc.php");
include_once("config.php");
$result = mysql_query("SELECT * FROM contacts ORDER BY park ASC");
$results = mysql_num_rows($result);
if ($results > 0){
$num=mysql_numrows($result);
$i=0;
while ($i < $num) {
$id=mysql_result($result,$i,"id");
$park=mysql_result($result,$i,"park");
?>
<tr>
<td style="background-color:;">
<?php echo $park; ?>
<br>
<?php if($park!=''){ ?>
<?php echo $id; ?>
<?php
}
?>
</td>
</tr>
<?php
$i++;
}
}
?>

Answer 1

There are two ways, you can do this.
Create all 200 rows on the database table and query it. This will omit almost all of the headache to get what you want.
Do a for loop from 1 to 200 and compare the active item if it exists on the mysql results. For this you require an continuous numeric entry in the database to identify each columns individually.
What I mean is? Column 1 in the should have corresponding record indicating 1 somewhere in its record.
Here is an example of this:
$result = mysql_query("SELECT * FROM contacts ORDER BY park ASC");
$results = mysql_num_rows($result);
if ($results > 0) {
$num=mysql_numrows($result);
$rows = array();
while($row = mysql_fetch_row($result)) {
$rows[$row['id']] = $row;
});
//Now process it
}

Answer 2

Try this:
<?php
include("dbinfo.inc.php");
include_once("config.php");
$spaces = range(1, 200);
$results = mysql_query("SELECT * FROM contacts ORDER BY park ASC");
$results_count = mysql_num_rows($result);
if ($results_count > 0) {
for ($i = 0; $i < $results_count; $i++) {
$parks[] = mysql_result($results, $i, "park");
}
}
?>
<table>
<tr>
<?php foreach ($spaces as $space): ?>
<td><?php echo $space ?></td>
<?php end foreach ?>
</tr>
<tr>
<?php foreach ($parks as $park): ?>
<td><?php if ($park > 0) { echo "$space"; } else { echo " "; } ?></td>
<?php end foreach ?>
</tr>
</table>
Start with this and tell me what you get.
Ok, I got it changed a little. Now it ahows me all from 1-200 and it shows the parking spaces values, but these values are not associated with the numbers. it looks to me like it puts them according to the id, for example in my table the customer on parking space 165 has the id 4 and therefore it doesnt put 165 to 165 but 165 to 4
<?php
include("dbinfo.inc.php");
include_once("config.php");
$spaces = range(1, 200);
$results = mysql_query("SELECT * FROM contacts");
$results_count = mysql_num_rows($results);
if ($results_count > 0) {
for ($i = 0; $i < $results_count; $i++) {
$parks[] = mysql_result($results, $i, "park");
}
}
?>
<table>
<tr>
<?php foreach ($spaces as $space){ ?>
<td><?php echo $space; ?></td>
<?php } ?>
</tr>
<tr>
<?php foreach ($parks as $park){ ?>
<td><?php if ($park!='') { echo $park.'<br>';} else { echo " "; } ?></td>
<?php }?>
</tr>
