[英]how to use data that we get from jquery, then use it in var with for loop?
[英]Assigning multiple data to var inside loop and trying to use var outside the loop
我有5条数据。
我将所有5条数据放入while循环内的变量中。 然后,我尝试在while循环之外使用use变量-但将所有放入的数据仍然回显。
目前,我可以放入数据,并成功取出1条数据。 我想回显所有5条数据。
码:
$s = <a search query that gets data from external db>
while($data = $r->FetchRow($s)) {
$addr = 'test address';
if($data['image'] == '') { $data['image'] = 'nophoto.jpg';}
$a = '<div style="height: 85px; width: 100%;"><img src="http://website.com/'.$data['image'].'" align="left" border="0" hspace="15" alt="Click for details" height="85px" width="120px" />'.$addr.'';
}
$m = "This is a test message <br />" .
$m = "".$a."" .
$m = "This is the end of a test message";
echo $m;
在循环中,您正在为$a
赋值。
因此,最新值将覆盖旧值,因此您将获得最后一个值。
如果要获取所有数据,则需要循环添加$a
。
更正的代码:
$a = '';
$s = <a search query that gets data from external db>
while($data = $r->FetchRow($s)) {
$addr = 'test address';
if($data['image'] == '') {
$data['image'] = 'nophoto.jpg';
}
$a .= '<div style="height: 85px; width: 100%;"><img src="http://website.com/'.$data['image'].'" align="left" border="0" hspace="15" alt="Click for details" height="85px" width="120px" />'.$addr.'';
}
$m = "This is a test message <br />" .
$m = "".$a."" .
$m = "This is the end of a test message";
echo $m;
