 Posted: Mon Jan 12, 2004 2:11 pm Post subject: SQL query SELECT DISTINCT and a problem with nested sections |
 |
|
Well, I'm spanish, and my english is very bad...
I have a problem when i want show a query with a clausule DISTINCT:
this is my table (`messages`):
| Code: | +----+--------+---------------------------+------------+
| id | name | text | date |
+----+--------+---------------------------+------------+
| 1 | juan | hola, hay alguien ahi? | 02/01/2004 |
+----+--------+---------------------------+------------+
| 2 | pedro | si, toi yo, jeje. | 02/01/2004 |
+----+--------+---------------------------+------------+
| 3 | juan | pos yo me tengo que pirar | 02/01/2004 |
+----+--------+---------------------------+------------+
| 4 | sergio | buenas tardes a todos!!! | 03/01/2004 |
+----+--------+---------------------------+------------+
| 5 | sergio | maņana nos vamos a cenar | 05/01/2004 |
+----+--------+---------------------------+------------+ |
and my code:
| Code: | <?
// connection and initialize the SmartyClass
$query = "SELECT DISTINCT `name` FROM `messages`";
$resp = mysql_query($query);
while ($datos = mysql_fetch_array($resp)) {
$smarty->append("DATOS", array(
"NAME" => $datos[name]
));
$query = "SELECT * FROM `messages` WHERE `name`='$datos[name]'";
$resp2 = mysql_query($query);
while ($datos2 = mysql_fetch_array($resp2)) {
$smarty->append("DATOS2", array(
"DATE" => $datos2[date],
"TEXT" => $datos2[text]
));
}
}
?> |
and my template:
| Code: | {section name=autor loop=$DATOS}
<h3>{$DATOS[autor].NAME}</h3>
{section name=msj loop=$DATOS2}
<p>{$DATOS2[msj].DATE}</p>
<p>{$DATOS2[msj].TEXT}</p>
{/section}
<hr />
{/section} |
but don't work as I want. I am beginner with Smarty, but the PHP code is correct, because i replace the smarty append x echo, de code result succes.
I need help, please. I think that the error is in the way of make the arrays(), but I don't know how make the second array() include in the first...
I don't explain very well, sorry ;) |

I would do something like this.
| Code: |
// connection and initialize the SmartyClass
$query = "SELECT DISTINCT `name` FROM `messages`";
$resp = mysql_query($query);
while ($datos = mysql_fetch_array($resp)) {
$new_line = array ();
$new_line['NAME'] = $datos['name'];
$query = "SELECT * FROM `messages` WHERE `name`='$new_line['NAME']'";
$resp2 = mysql_query($query);
while ($datos2 = mysql_fetch_array($resp2)) {
$new_line['DATAS'][] = array ('DATE'=>$datos2['date'], 'TEXT'=>$datos2['text']);
}
$smarty->append ('DATOS', $new_line);//stores the new line.
}
?>
|
Now your template.
| Code: |
{foreach from=$DATOS item=line}
<h3>{$line.NAME}</h3>
{foreach from=$line.DATAS item=infos}
<p>{$infos.DATE}</p>
<p>{$infos.TEXT}</p>
{/foreach}
{/foreach}
|
I'm not sure I got it well, but this should work.
EDIT: Codewise, you may want to do only one request to get name & messages. While writing my answer, I hadn't realize there was only one table. |

don't work it :(
Parse error: parse error, unexpected T_STRING, expecting ']' in c:\Apache2\htdocs\toxico\plugins\smarty\templates_c\pruebaphp.html on line 4
and this is the template_compiled:
[php:1:b3b74fefb0]<?php /* Smarty version 2.5.0, created on 2004-01-12 17:25:06
compiled from pruebaphp.html */ ?>
<?php if (count((array)$this->_tpl_vars['DATOS'])):
foreach ((array)$this->_tpl_vars['DATOS'] as $this->_tpl_vars['$this->_tpl_vars['line']']): //this is the line 4
?>
<h3><?php echo $this->_tpl_vars['line']['NAME']; ?>
</h3>
<?php if (count((array)$this->_tpl_vars['line']['DATAS'])):
foreach ((array)$this->_tpl_vars['line']['DATAS'] as $this->_tpl_vars['$this->_tpl_vars['infos']']):
?>
<p><?php echo $this->_tpl_vars['infos']['DATE']; ?>
</p>
<p><?php echo $this->_tpl_vars['infos']['TEXT']; ?>
</p>
<?php endforeach; endif; ?>
<?php endforeach; endif; ?>[/php:1:b3b74fefb0]

Weird, I've tested this exact template on my system......
{foreach from=$DATAOS item=line}
<h3>{$line.NAME}</h3>
{foreach from=$line.DATAS item=infos}
<p>{$infos.DATE}</p>
<p>{$infos.TEXT}</p>
{/foreach}
{/foreach}
Did you put a "$" in "item=hereline" ? (wich is wrong) |
