我有问题显示图片url-link到我的showdb.php
我目前的数据库记录:
|的 _id _____ | ____名_____ | _image |
| ____ 1 _____ | __banana ____ |了banana.jpg |
| ____ 2 _____ | __aple ______ | apple.jpg |
当我在record.php中显示时,我想做的是banana.jpg或image下的栏目是www.myhost.com/image/banana.jpg吗?
我现在得到的结果:
{"posts":[
{
"name":"banana",
"image":banana.jpg}, // FROM THIS
{
"name":"apple",
"image":apple.jpg} // FROM THIS
]}
我想要的是:
{"posts":[
{
"name":"banana",<br>
"image":www.myhost.com/image/banana.jpg}, // BECOME THIS
{
"name":"apple",<br>
"image":www.myhost.com/image/apple.jpg} // BECOME THIS
]}
这是我目前显示我的数据库记录的代码:
if ($rows) {
$response["success"] = 1;
$response["message"] = "Post Available!";
$response["posts"] = array();
foreach ($rows as $row) {
$post = array();
$post["name"] = $row["name"];
$post["image"] = $row["image"];
//update our repsonse JSON data
array_push($response["posts"], $post);
}
// echoing JSON response
echo json_encode($response);
} else {
$response["success"] = 0;
$response["message"] = "No Post Available!";
die(json_encode($response));
}
是否可以更改这些代码?
或者如果有任何链接这样做,我很高兴:))
谢谢你的回答:)))*抱歉,如果我的英语不好:)

解决:@KhaledBentoumi
添加
'www.yourhost.com/folder/'(dot)$row["image"]; => 'www.yourhost.com'.$row["image"];
但是,它会将/
更改为\/
:'www.yourhost.com\/folder\/file.jpg
添加JSON_UNESCAPED_SLASHES
,例如:
$url = 'http://www.example.com/';
echo json_encode($url), "\n";
echo json_encode($url, JSON_UNESCAPED_SLASHES), "\n";
快乐的编码家伙! :))

只需将www.myhost.com/image/
附加到帖子数组中的图像条目
if ($rows) {
$response["success"] = 1;
$response["message"] = "Post Available!";
$response["posts"] = array();
foreach ($rows as $row) {
$post = array();
$post["name"] = $row["name"];
$post["image"] = 'www.myhost.com/image/'.$row["image"]; // Append here
//update our repsonse JSON data
array_push($response["posts"], $post);
}
// echoing JSON response
echo json_encode($response);
} else {
$response["success"] = 0;
$response["message"] = "No Post Available!";
die(json_encode($response));
}

使用简单连接:
$post["image"] = "www.myhost.com/image/".$row["image"];
