hi, i have a mysql code that yesterday was working perfectly, but today it says that its wrong! here is the code:
Code:
$conexion = mysql_connect($host,$user,$pass);
                  
if(!$conexion){
echo '<p style="font-size:large;">Conexión fallida</p>';
}else{
mysql_select_db('test');
$query = 'SELECT id, titulo, contenido, autor, fecha FROM avisos WHERE 1=id';
$result = mysql_query($query);
while($row = mysql_fetch_array($result)){
$titulo = $row['titulo'];
$contenido = $row['contenido'];
$autor = $row['autor'];
}
}
mysql_close();

and the error:
Code:
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/alalex/domains/webot.frih.net/public_html/pumarin/avisos.php on line 123

Warning: mysql_free_result(): supplied argument is not a valid MySQL result resource in /home/alalex/domains/webot.frih.net/public_html/pumarin/avisos.php on line 128

Try and use this for the query:
Code:

$query = "SELECT id, titulo, contenido, autor, fecha FROM avisos WHERE 1='id'";

Plus check to see if everything is spelled correctly.

it keeps on saying:
Code:
mysql_num_rows: supplied argument is not a valid MySQL result resource
hexkid
Code:
$result = mysql_query($query);
### add these lines after the mysql_query() call
if (!$result) {
  echo '<p style="font-size:large;">Query fallida.</p>';
  echo '<p style="font-size:large;">Query: <tt>', $query, '</tt></p>';
  echo '<p style="font-size:large;">Razón: <tt>', mysql_error(), '</tt></p>';
}

The database 'test' is not a normal database like your others. It is shared all other users and is automatically reset at certain intervals (days or hours or something). Create a new database in Direct Admin and use that instead.

Code:

$sql = "SELECT * FROM TABLENAME";
$resource = mysql_query($sql):
$num = mysql_num_rows($resource);

//Then to see how many there is:
echo $num;

That's like buying the entire annual production of a computer manufacturing company when all you want is a mouse.

Yeah but it works. I know you can do: Count(*) but i just thought of the other way then.

ok, i was using mysql_num_rows before, but it said it wasnt valid! it was because there was no mysql table! i think i have a problem in my phpMyAdmin because everytime i create a table it dissapears in about a day Sad
alalex
ooo, i know why it was! it was because i was using the database test! and it got reset every day! Confused thanks anyways Very Happy
