php displaying mysqli array

[JimmyLeaman]

Hey All.

 

I'm currently using the following code to source some information from a Mysql Database.

 

I've limited the results to 6 Values. I'm using the WHILE function to display a table with the results populated in.

 

As you'll see from the attached picture, the WHILE function is causing 5 tables to be created, each with 5 of the same image displayed. How do I go about displaying only 1 table with the 5 different pictures displayed in?

<?php

$result = mysqli_query($con, "SELECT * FROM photo ORDER BY id DESC LIMIT 6"); 
while($row = mysqli_fetch_array($result)){

echo
'<table>
<tr><td class="left">

<a href="photo.php?id='.$row['id'].'"><img src="images/'.$row['id'].'.jpg"  height="232"  alt=""/></a>


</td>
<td class="center">
<a href="photo.php?id='.$row['id'].'"><img src="images/'.$row['id'].'.jpg"  height="112"  alt=""/></a>
<a href="photo.php?id='.$row['id'].'"><img src="images/'.$row['id'].'.jpg"  height="112"  alt=""/></a>
</td>
<td class="right">

<a href="photo.php?id='.$row['id'].'"><img src="images/'.$row['id'].'.jpg"  height="72"  alt=""/></a>
<a href="photo.php?id='.$row['id'].'"><img src="images/'.$row['id'].'.jpg"  height="72"  alt=""/></a>
<a href="photo.php?id='.$row['id'].'"><img src="images/'.$row['id'].'.jpg"  height="72"  alt=""/></a>

</td></tr></table>';
}
?>

 

Thanks

You have a loop in which you create a table and show the exact same information 5 times.  What do you think  your output will be???

 

While it may be a small misnomer, the mysqli_fetch_array fetches an "array of the fields of one record" of the results.  Not an array of all the records.  Therefore your loop is processing just one result record at a time.  Consequently you have to go thru the loop 6 times(?) to get all the records.  Thus it would make sense to only create the table one time - before the loop begins, with the end tag after the loop ends.

 

Of course a quick read of this function in the php manual might have made this immediately clear.

Ok, thanks for your response.

 

Unfortunately I don't have the same degree of knowledge at the moment, could you maybe point me in the right direction?

 

I know I could use something like this which would stop 5 tables being shown, however each image needs to have it's own styling, image size.. etc.

<table><tr>
<?php

while($row=mysqli_fetch_array($result)){

echo '

<td><img src="images/'.$row['id'].'.jpg"></td>

';
}
?>
</tr><table>

That code is correct.  Where are you getting the attributes you speak of?  Are they part of the query results?  If so , just use them to form your img tag.  If not, how do you expect to assign them to each image?

Assuming that there are always 6 images and you want the images to always be positioned and sized the same, you could:

1. Read the values into an array
2. Output the images into a table
3. Use CSS to position and size the images

 

Here is a quick and crude example:

<?php
$images = array();
$result = mysqli_query($con, "SELECT * FROM photo ORDER BY id DESC LIMIT 6"); 
while($row = mysqli_fetch_assoc($result)) {
     $images[] = '<a href="photo.php?id='.$row['id'].'"><img src="images/'.$row['id'].'.jpg" alt=""/></a>';
}
?>
<style type="text/css">
table .left { width:200px; }
table .left img { width:200px; height:232px; }
table .center { width:100px; }
table .center img { width:100px; height:112px; }
table .right { width:50px; }
table .right img { width:50px; height:72px; }
</style>
<table>
     <tr>
          <td class="left"><?php   print $images[0]                            ?></td>
          <td class="center"><?php print $images[1] . $images[2];              ?></td>
          <td class="right"><?php  print $images[3] . $images[4] . $images[5]; ?></td>
     </tr>
