I´m fetching an array from a mysql query like this.
$viewerSQL = mysql_query("SELECT * FROM `this` WHERE id = ".
mysql_real_escape_string($_GET[id]) ."");
$pageData = mysql_fetch_array($pageSql);
I get an array with like 40 entries, i want to check seven of them by name if they are filled.
What i´ve tried and what I thought about so far:
$oioi = 0;
while($oioi<7){
$oioi++;
$pic = "pic".$oioi;
$active="";
$path = "./upload/objectoffers/$viewerData[id]/$pic";
$picDesc = "pic".$oi."Desc";
$picArray = '$viewerData['.$pic.']';
echo $pic."<br>";
echo $picArray."<p>";
if(!empty($path)){
if($oioi==1){$active = "active";}?>
<div class="item <?=$active;?>">
<img style="width: 100%;" src="./images/<?=$viewerData[$pic];?>" alt="<?=$viewerData[$picDesc]?>">
</div>
<?
}}
?>
But this doesn´t work because: $path
is NEVER empty...I wanted to avoid to write "if(!empty)
" for every single $viewerData[pic1]
to $viewerData[pic7]
array manual...
that´s why i´m here...
maybe you can help me improving this or offer some tips.
Thanks!
edit: This is what I get as "output":
pic1
$viewerData[pic1]
pic2
$viewerData[pic2]
pic3
$viewerData[pic3]
pic4
$viewerData[pic4]
pic5
$viewerData[pic5]
pic6
$viewerData[pic6]
pic7
$viewerData[pic7]
