Show more than one result from JOIN with if statement - php

I have this JOIN, that gets me more than on result:
at.tipo AS atividade,
at.data AS datacadastro,
at.user AS usercadastro,
LEFT JOIN atividades at
ON (at.produto = '$produto')
AND (at.tipo = 'cadastra' OR at.tipo = 'revisado')
And I have: if string = 'cadastra' shows something, if string = 'revisado' shows something else.
<?php
if ($row['atividade'] == 'cadastra') {
echo '<div id="user-img">';
echo '<img src="http://'.$row['imguser'].'"/></div>';
echo '<div id="user-cadastro" class="greytxt">';
echo 'Cadastrado por <br>' .$row['usercadastro']. '<br>em ';
echo $row['datacadastro']. '</div>';
}
?>
<?php
if ($row['atividade'] == 'revisado') {
echo '<div id="user-img">';
echo '<img src="http://'.$row['imguser'].'"/></div>';
echo '<div id="user-cadastro" class="greytxt">';
echo 'Cadastrado por <br>' .$row['usercadastro']. '<br>em ';
echo $row['datacadastro']. '</div>';
}
?>
The problem is, it's showing just the first result, and not all.
How can I display all results?
EDIT:
I have this JOIN inside a big query, that give me other important rows.
But I just want one result for this principal query (WHERE = $produto), and want more results from my JOIN table.
$rows = $result->num_rows;
for ($j = 0; $j < $rows; ++$j) {
$result -> data_seek($j);
$row = $result->fetch_array (MYSQLI_ASSOC);
?>
My result should be this, but JOIN shows just row 'cadastra'.

Use $result->fetch_array (MYSQLI_ASSOC) inside a while loop
while ($row = $result->fetch_array (MYSQLI_ASSOC)) {
if ($row['atividade'] == 'cadastra')
{
echo '<div id="user-img">';
echo '<img src="http://'.$row['imguser'].'"/></div>';
echo '<div id="user-cadastro" class="greytxt">';
echo 'Cadastrado por <br>' .$row['usercadastro']. '<br>em ';
echo $row['datacadastro']. '</div>';
} ?>
<?php if ($row['atividade'] == 'revisado')
{
echo '<div id="user-img">';
echo '<img src="http://'.$row['imguser'].'"/></div>';
echo '<div id="user-cadastro" class="greytxt">';
echo 'Cadastrado por <br>' .$row['usercadastro']. '<br>em ';
echo $row['datacadastro']. '</div>';
}
}

foreach() Loop Outputting Data and Creating Layout

I am currently trying to create a class schedule which I pull from my Sql Server database with PHP and I am trying to get the layout output as well as the data as I am grouping the resources.
These groupings are nested such as:
-DAY
--TIME
---CLASS
----STUDENTS
And should output like this:
However, I am getting this:
My current output is working, however, it is only on the first loop, then everything goes haywire. I am assuming there is an erroneous </div> tag somewhere in my code yet I cannot for the life of me find it.
My php code is a function that is delcare as such:
<div class="mainScheduleWrapper">
<?php daySchedule(); ?>
</div>
My php code is as such:

Any help would be greatly appreciated - even if it's to tell me I'm going about it the completely wrong way.

I wouldn't say you're going about it the completely wrong way, but a few red flags jumped out at me in your code.
The use of goto jumping is bad practice. It butchers your program flow and forces you to segregate tasks that shouldn't be kept apart. You marked the sections of code "// NON CLOSED" when there was a </div> missing, is there any purpose for that? How do you know the goto sections are reliable?
When you echo something like <div class="col">, without escaping the double-quotes (as in \" for every " character), it can be problematic. Your code can get mangled or misinterpreted, both on the PHP end or on the HTML end.
Like others have said, the use of PHP may be overkill here. Besides just sending the JSON, the rest could be handled with JavaScript.

different get_rows from the database

This is the function im using to show results in the index.php with the style.css correctly done with the li´s and the div´s all that i just want to show in every li the price or the service i want. EXAMPLE: ($_GET_ROW['ID'] = '1', $_GET_ROW['ID'] = '2').
function products() { $get = mysql_query('SELECT id, servico, preco FROM loja');
if (mysql_num_rows($get)==0) {
echo "Não existem produtos a serem mostrados!";
} else {
while ($get_row = mysql_fetch_assoc($get)) {
echo '<li class="l1 i1 column1">';
echo '<h2>'.**$get_row["servico"]**. '</h2>';
echo '<div class="basket">Adicionar</p></div>';
echo '<div class="preco"><em>Preco:</em><strong>'.number_format($get_row['preco'], 2).'</strong><span>EUR</span>';
echo '</div>';
echo '<li class="l2 i0 column0">';
echo '<h2>'**.$get_row["servico"].**'</h2>';
echo '<div class="basket">Adicionar</p></div>';
echo '<div class="preco"><em>Preco:</em><strong>'.number_format($get_row['preco'], 2).'</strong><span>EUR</span>';
echo '</div>';
My database:
-----------------------------------
id servico preco
-----------------------------------
1 Servico Normal 29.5
-----------------------------------
2 Servico Rapido 32.5
-----------------------------------
It seems like you need a while loop to iterate through the rows like so:
if (mysql_num_rows($get)==0) {
echo "Não existem produtos a serem mostrados!";
} else {
while($get_row = mysql_fetch_assoc($get)) {
**echo '<li class="l1 i1 column1">';
echo '<h2>'.$get_row["servico_normal"].'</h2>';
echo '<div class="basket">Adicionar</p></div>';
echo '<div class="preco"><em>Preco:</em <strong>'.number_format($get_row['preco'], 2).'</strong><span>EUR</span>';
echo '</div>';**
}
}
However, you should immediately stop using mysql_ functions as they are being deprecated and vulnerable to SQL injection; and use mysqli_ or PDO instead.
Update 1
mysql_ functions are officially deprecated.
The principle of my initial answer still remains. You have two rows in your database and you want to iterate through them.
while ($get_row = mysql_fetch_assoc($get)) {
$liClass = 'l' . $get_row[id];
echo '<li class="' . $liClass . ' i1 column1">';
echo '<h2>' . $get_row[servico] . '</h2>';
echo '<div class="basket"><p>Adicionar</p></div>';
echo '<div class="preco"><em>Preco:</em><strong>' . number_format($get_row['preco'], 2) . '</strong><span>EUR</span>';
echo '</div>';
}
For the first row, the output would be:
<li class="l1 i1 column1">
<h2>Servico Normal</h2>
<div class="basket"><p>Adicionar</p></div>
<div class="preco"><em>Preco:</em><strong>29.50</strong><span>EUR</span></div>

PHP while loop split into two

I'm running a while loop which is taking rows from mySQL and echo'ing them out. Pretty standard. However, there needs to be different HTML markup for the first item, next two items, then it continues as normal into the while loop.
Currently, my while loop looking something like this:
while( ( $row = mysql_fetch_object( $result ) ) !== false )
{
// Places ad based of predefined variable frequency
if ($ad == $adFrequency){
echo '<div class="one-advertisement-article clearfix">';
echo '<div class="grid_9 suffix_2"><img src="http://placehold.it/263x75/000000/ffffff"></div>';
echo '<div class="grid_1"><a class="navigate-right-icon ss-icon" href="#">navigateright</a></div>';
echo '</div>';
$ad = 0;
}
echo '<div class="one-news-article clearfix">';
if( $row->imagelibid )
{
$imageid = intval( $row->imagelibid );
$image_result = mysql_query( "SELECT * FROM imagelib WHERE id = {$imageid}", $db );
$image_row = mysql_fetch_object( $image_result );
$image_url = "http://www.#.com/slir/w280/imagelib/" . $image_row->id . "_" . $image_row->filename;
echo '<div class="grid_4"><img src="'.$image_url.'"></div>';
}
else {
echo '<div class="grid_4"><div class="news-placeholder"><span class="ss-icon">ellipsischat</span></div></div>';
}
echo '<div class="grid_7">';
echo '<h2>'.$row->title.'</h2>';
$published_date = date('D, d M Y', strtotime($row->datein));
echo '<p class="published-date">'.$published_date.'</p>';
echo '</div>';
echo '<div class="grid_1">';
echo '<div class="news-item-vertical-sep"> </div>';
echo '<p></p>';
echo '</div>';
echo '</div>';
$ad++;
}
This works fine, but I need to take the first three news items and use this:
echo ' <div class="one-news-featured-article clearfix">';
echo ' <div class="grid_12">';
if( $row->imagelibid )
{
$imageid = intval( $row->imagelibid );
$image_result = mysql_query( "SELECT * FROM imagelib WHERE id = {$imageid}", $db );
$image_row = mysql_fetch_object( $image_result );
$image_url = "http://www.#.com/slir/w280/imagelib/" . $image_row->id . "_" . $image_row->filename;
echo '<div class="large-featured-image-container"><img src="'.$image_url.'">/div>';
}
echo ' <div>';
echo ' <h2>'.$row->title.'</h2>';
echo ' </div>';
echo ' </div>';
echo ' </div>';
echo ' <div class="grid_6">';
Any help? Essentially, it needs to apply the second code to the first three items in the query, then follow through with the code included in the current while loop - like an offset I guess.
Thanks,
R
This is quite simple. I hope I understood your question correctly:
$i = 0;
while ( ( $row = mysql_fetch_object( $result ) ) !== false ) {
if ($i < 3) {
// First code
} else {
// Second code
}
$i += 1;
}
Firstly, you should avoid using any mysql_ functions as they are all deprecated and will be removed from future versions of PHP. I'd recommend using PDO instead. See this tutorial to get started.
Then, it'll simply be a case of doing something like this:
foreach($db->query($query) as $index => $row) {
if ($index < 3) {
// first 3 items
} else {
// other items
}
}
You can do it easaly with an simple counter and an if statement:
$count = 0;
while(fetching) {
if($count < 3) {
// items 1, 2 and 3
} else {
// do normal
}
$count++;
}

Listing diary events grouped by days in PHP/MySQL

I'm trying to list diary events in PHP from a MySQL database, but grouped by days. I'll explain.
This is a screenshot of what I have so far:
As you can see there are two diary events for the 23rd October 2012 and is showing two calendar icons/representations/whatever's. I actually want it to show one calendar icon on the left but list all of that days events on the right, until the next day - as seen in my a̶r̶t̶i̶s̶t̶s̶ idiots impression below:
This is the code I have just written, could somebody please point me in the right direction:
$SQL = "SELECT entry_id, entry_title, entry_body, entry_date, entry_day, entry_month, entry_year ";
$SQL .= "FROM pages_diary WHERE entry_month = :this_month AND entry_year = :this_year ";
$SQL .= "ORDER BY entry_date DESC;";
// PDO stuff
if ($STH->rowCount() > 0) {
while($row = $STH->fetch()):
$this_db_month_word = mktime(0, 0, 0, $row['entry_month']);
$this_db_month_word = strftime("%b", $this_db_month_word);
echo '<div class="diary_events_item" id="diary_events_item_'.$row['entry_id'].'">';
echo '<div class="diary_events_item_left">';
echo '<div class="calendar_wrap">';
echo '<div class="calendar_wrap_top">';
echo $this_db_month_word;
echo '</div>';
echo '<div class="calendar_wrap_bottom">';
echo str_pad($row['entry_day'],2,'0',STR_PAD_LEFT);;
echo '</div>';
echo '</div>';
echo '</div>';
echo '<div class="diary_events_item_right">';
echo '<strong>'.htmlspecialchars($row['entry_title']).'</strong><br>';
echo '<p>'.htmlspecialchars($row['entry_body']).'</p>';
echo '</div>';
echo '<div class="clear"></div>';
echo '</div>';
endwhile;
} else {
echo '<p>There are no diary entries logged for <strong>'.$this_month_word.' '.$this_year.'</strong>.</p>';
}
Not looking for exact code (although that would be spiffing), just an explanation would do, I'm sure I can work it out from that.
THE FIX
At the end of the WHILE loop, I added:
$last_db_day = $row['entry_day'];
And then wrapped the calendar item in:
if ($last_db_day != $row['entry_day']) {
echo '<div class="calendar_wrap_top">';
echo $this_db_month_word;
echo '</div>';
echo '<div class="calendar_wrap_bottom">';
echo str_pad($row['entry_day'],2,'0',STR_PAD_LEFT);;
echo '</div>';
}
As you loop over your resultset from the database, keep track of the last entry_date that you've seen and only output a new calendar icon if the current record is for a different date.
I usually do this as follows:
if ($STH->execute()) {
// output headers
$row = $STH->fetch();
while ($row) {
$current_date = $row['entry_date'];
// output $current_date initialisation
do {
// output event $row
} while ($row = $STH->fetch() and $row['entry_date'] == $current_date);
// output $current_date termination
}
// output footers
}
Although I would go the other way around and embed the PHP within the HTML rather then the other way around, here is what I would do using your code:
$SQL = "SELECT entry_id, entry_title, entry_body, entry_date, entry_day, entry_month, entry_year ";
$SQL .= "FROM pages_diary WHERE entry_month = :this_month AND entry_year = :this_year ";
$SQL .= "ORDER BY entry_date DESC;";
// PDO stuff
if ($STH->rowCount() > 0) {
$loopDay = '';
while($row = $STH->fetch()):
if ($row['entry_day'] != $loopDay) {
$loopDay = $row['entry_day'];
$changed = true;
}
$this_db_month_word = mktime(0, 0, 0, $row['entry_month']);
$this_db_month_word = strftime("%b", $this_db_month_word);
echo '<div class="diary_events_item" id="diary_events_item_'.$row['entry_id'].'">';
echo '<div class="diary_events_item_left">';
if ($changed) {
echo '<div class="calendar_wrap">';
echo '<div class="calendar_wrap_top">';
echo $this_db_month_word;
echo '</div>';
echo '<div class="calendar_wrap_bottom">';
echo str_pad($row['entry_day'],2,'0',STR_PAD_LEFT);;
echo '</div>';
echo '</div>';
} else {
echo ' ';
}
echo '</div>';
echo '<div class="diary_events_item_right">';
echo '<strong>'.htmlspecialchars($row['entry_title']).'</strong><br>';
echo '<p>'.htmlspecialchars($row['entry_body']).'</p>';
echo '</div>';
echo '<div class="clear"></div>';
echo '</div>';
$changed = false;
endwhile;
} else {
echo '<p>There are no diary entries logged for <strong>'.$this_month_word.' '.$this_year.'</strong>.</p>';
}

divide php mysql result left and right

$flag=0;
if($q->num_rows > 0) :
echo '<div id="testimonial">';
while($r = $q->fetch_array(MYSQLI_ASSOC)) :
if($flag=0) :
$class=test1; $flag=1;
else :
$class=test2; $flag=0;
endif;
echo '<div class="'.$class.'">';
echo '<span class="left">';
echo '<p>'.$r['compname'].'</p>';
echo '<p>'.$r['position'].'</p>';
echo '</span>';
echo '<span class="right">';
echo '<p>'.$r['testimonial'].'</p>';
echo '</span>';
echo '</div>';
endwhile;
echo '</div>';
else :
echo '<h1>Coming Soon</h1>';
endif;
i want the result look like the picture! seems my php code doesnt work out the css class. its only showing 1 class test1 when i echoing the result. so all the result left align.
if($flag=0)
^ should be ==
This is easier though with:
$i = 0;
while (…) {
$class = $i++ % 2 ? 'test1' : 'test2';
}
You have an assignment in your if statement instead of a comparison: if($flag=0).
$class=test1; $flag=1;
^----^---
you're missing some quotes there too. As it stands now, you're trying to assign a constant named "test1" and "test2", which are most likely not defined, so they'll evaluate to an empty string.
$flag=0;
if($q->num_rows > 0) :
echo '<div id="testimonial">';
while($r = $q->fetch_array(MYSQLI_ASSOC)) :
if($flag==0) :
$class='test1'; $flag=1;
else :
$class='test2'; $flag=0;
endif;
echo '<div class="'.$class.'">';
echo '<span class="left">';
echo '<p>'.$r['compname'].'</p>';
echo '<p>'.$r['position'].'</p>';
echo '</span>';
echo '<span class="right">';
echo '<p>'.$r['testimonial'].'</p>';
echo '</span>';
echo '</div>';
endwhile;
echo '</div>';
else :
echo '<h1>Coming Soon</h1>';
endif;
This should work!
