Setting an interval on do / while from 5 to 5 - php

Question

I've made a repeat region with dreamweaver and the result is this:
<div>
<?php do { ?>
<div class="slide">
<img src="<?php echo $row_Recordset1['imagemUrl']; ?>" />
<h2><?php echo $row_Recordset1['titleProj']; ?></h2>
</div>
<?php while ($row_Recordset1 = mysql_fetch_assoc($Recordset1)); ?>
</div>
No problem here, it works fine.
The thing is, I'm trying to use only 5 slides for each page, something like this:
<div>
<div class="page">
<?php do { ?>
<div class="slide">
<img src="<?php echo $row_Recordset1['imagemUrl']; ?>" />
<h2><?php echo $row_Recordset1['titleProj']; ?></h2>
</div>
<?php
$i = 0;
$r = $i % 5;
$i++;
if ( $r == 0 ) {
?>
</div> <!-- closes div.page -->
<div class="page"> <!-- adds a new div.page -->
<? } ?>
<?php while ($row_Recordset1 = mysql_fetch_assoc($Recordset1)); ?>
</div>
It's obviously not working, but hopefully you'll see what I'm trying to reach.
Thanks in advance!
UPDATE:
The result i get is:
<div class="page">
<div class="slide">...</div>
<div class="slide">...</div>
<div class="slide">...</div>
<div class="slide">...</div>
<div class="slide">...</div>
<div class="slide">...</div>
<div class="slide">...</div>
<div class="slide">...</div>
</div>
I would like it to be:
<div class="page">
<div class="slide">...</div>
<div class="slide">...</div>
<div class="slide">...</div>
<div class="slide">...</div>
<div class="slide">...</div>
</div>
<div class="page">
<div class="slide">...</div>
<div class="slide">...</div>
<div class="slide">...</div>
</div>

Answer 1

You're setting $i to 0 on every iteration. Place the $i = 0 before the do-while loop.
You should probably also place $i++ before $r = $i % 5; to get the result you require.
EDIT: You're also missing a closing brace before your while statement (typo?)
Hence, the complete code:
<div>
<div class="page">
<?php
$i = 0;
do { ?>
<div class="slide">
<img src="<?php echo $row_Recordset1['imagemUrl']; ?>" />
<h2><?php echo $row_Recordset1['titleProj']; ?></h2>
</div>
<?php
$i++;
$r = $i % 5;
if ( $r == 0 ) {
?>
</div> <!-- closes div.page -->
<div class="page"> <!-- adds a new div.page -->
<?php
}
} while ($row_Recordset1 = mysql_fetch_assoc($Recordset1)); ?>
</div>

Answer 2

the piece you gave is not a valid php code.
the line here:
<h2><?php echo $row_Recordset1['titleProj']; ?></h2>
opens a php tag without closing it before the next one you open.. so a first step would be to change that line to
<h2><?php echo $row_Recordset1['titleProj']; ?></h2>
also you missed closing a block, here:
<? } ?>
you should close both the if and the do/while block (so another })
another problem is the fact that on every step you change $i to 0, so every time $r will be 0 also
so in conclusion: take your problems step by step as you have more than one

Answer 3

<div>
<div class="page">
<?php for ($i = 0; $row_Recordset1 = mysql_fetch_assoc($Recordset1); $i++) { ?>
<div class="slide">
<img src="<?php echo $row_Recordset1['imagemUrl']; ?>" />
<h2><?php echo $row_Recordset1['titleProj']; ?></h2>
</div>
<?php if ( $i % 5 == 0 && $i ) { ?>
</div> <!-- closes div.page -->
<div class="page"> <!-- adds a new div.page -->
<?php } ?>
<?php } ?>
</div>
</div>

Answer 4

Something like this would loop through 5 times adding a new <div>content</div> to the variable $html. You can then echo the variable in your html body.
$html = "";
for ($i=0;$i<5;$i++) {
$html .= "<div class=\"page\">". $content[$i] . "</div>\n";
}
Additions:
<?PHP
while ($row_Recordset = mysql_fetch_assoc($Recordset1)) {
$html .= "<div class='page'>\n";
for ($i=0;$i<5;$i++) {
$html .= "<div class='slide'>". $row_Recordset[$i]['column'] . "</div>\n";
}
$html .= "</div>\n";
}
?>
This code will loop through the recordset populating $html on each iteration. Try echo $html and you will have an output structured as you want.
