嘿伙计们,我试图使用foreach从我的数据库中检索值,但表中的一个字段/行是我序列化到数据库中的数组。我没有问题检索此值,但当我尝试从数据库中获取数组值时。他们加起来是下一个值。即如果第一个数组计数为5且第二个数组计数为3,则在显示第二行时,它会给出8个结果,而不是3个,这是我的代码,如下所示。
$imageDisplay->getall('images',array('id', 'ASC' ));
if (!$imageDisplay->count()) {
# code...
$imagelist = "<h2>No Images Yet</h2>";
}
else {
$x = 0;
foreach ($imageDisplay->results() as $imageDisplay) {
$event = $imageDisplay->event;
$cover = $imageDisplay->image_cover;
$image = unserialize($imageDisplay->image);
$date = $imageDisplay->date;
foreach ($image as $key => $image) {
# code...
$imageset .= "<img src='../images/".$event."/".$image."' />";
$x++;
}
$imagelist .= "<div class='servicelist'><br /><h2>". $event ."</h2><br><img src='../images/". $cover ."' />
<div class='clear'></div>".$imageset."
<span> <a href='index.php?navsection=gallery&editgallerySection=".$imageDisplay->id."'>Edit</a> <a href='index.php?navsection=gallery&deleteID=".$imageDisplay->id."'>Delete</a></span></div><div class='clear high'></div>";
#$x++;
}
}
并且图像数组是
Array
(
[0] => Array
(
[0] => event1.jpg
[1] => event2.jpg
[2] => event3.jpg
[3] => event4.jpg
[4] => event5.jpg
)
[1] => Array
(
[0] => event1.jpg
[1] => event2.jpg
[2] => event3.jpg
[3] => event4.jpg
[4] => event5.jpg
[5] => event6.jpg
[6] => event7.jpg
[7] => event8.jpg
[8] => event9.jpg
)
[2] => Array
(
[0] => bkg-03.png
[1] => oil.png
[2] => yamaha.jpg
[3] => yamaha2.jpg
)
)
当我回显imageList变量时,图像相加,使得第二行图像=第一行图像+第二行图像等等 搜索了很多,但大多数结果是用于将值输入数据库。提前致谢
答案 0 :(得分:1)
变量$imageset
未重置。请注意,在第二个foreach中它接收自己,加上前一个。立即尝试:
$imageDisplay->getall('images',array('id', 'ASC' ));
if (!$imageDisplay->count()) {
# code...
$imagelist = "<h2>No Images Yet</h2>";
}
else {
$x = 0;
foreach ($imageDisplay->results() as $imageDisplay) {
$event = $imageDisplay->event;
$cover = $imageDisplay->image_cover;
$image = unserialize($imageDisplay->image);
$date = $imageDisplay->date;
$imageset = '';
foreach ($image as $key => $image) {
# code...
$imageset .= "<img src='../images/".$event."/".$image."' />";
$x++;
}
$imagelist .= "<div class='servicelist'><br /><h2>". $event ."</h2>
<br>
<img src='../images/". $cover ."' />
<div class='clear'></div>".$imageset."
<span>
<a href='index.php?navsection=gallery&editgallerySection=".$imageDisplay->id."'>
Edit
</a>
<a href='index.php?navsection=gallery&deleteID=".$imageDisplay->id."'>
Delete
</a>
</span></div><div class='clear high'></div>";
# $x++;
}
}
