Your problem seems to stem from the $content .= $row; $row is an Array and
you must use an index to get at any given value it holds. If you need all of
the values in $row, use the count() function to get the number of elements
(columns in this case), then loop through them adding them to $content along
with any separators (IE: commas or semi colons or spaces) etc. the code
might look like this:
$content = ""; // I like to make sure that the variable is always
initialized to something before I use it.
$num_results_cat = mysql_num_rows($result_cat);
for ($i=0; $i < $num_results_cat; $i++)
{
$row = mysql_fetch_array($result);
$num_of_cols = count($row);
for ($x=0; $x<$num_of_cols; $x++)
{
$content .= ", ".$row[$x];
}
}
This will allow you to loop through every row in the query and add every
column to the $content variable.

Subject: [PHP-DB] Can't see the results
Hello guys
Thanks to all those you helped me with y the question I made before (not a
valid MySQL result) it's working now.
Now, I want to display the result of my search with the following code:
if($code){
$query_cat = "select author.author_names || ' '|| author.author_surnames
as full_name from author, authorxcat
where authorxcat.cat_code = $code
and author.author_code = authorxcat.author_code"
or die($mysql_error());
$result_cat = mysql_query($query_cat);
$num_results_cat = mysql_num_rows($result_cat);
for ($i=0; $i < $num_results_cat; $i++)
{
$row = mysql_fetch_array($result);
$content .= $row;
/*
$content .= htmlspecialchars(stripslashes($row["author_names"]))
." ".htmlspecialchars(stripslashes($row ["author_surnames"]))."<br>";*/
}
}
But I just get the following:
ArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArray
I also tried to do it commenting the "$content .= $row;" and uncommenting
the lines that are commented in the code but I just get a blank page.
What am I doing wrong?
Thanks a lot for your help.
