小程序前台可以显示出文字内容 然而图片显示不了，为什么?

Question

xhtml:<!--首页-->
<view hidden="{{currentTab!==0}}">
<view wx:for='{{logs}}'>

<view>{{logs.pcontent}}</view>
<view>
<!-- <image wx:for='{{logs.ppic}}' wx:for-index="index" wx:for-item='picPath' src='{{picPath.src}}'></image> -->
<image src='{{logs.ppic[item]}}'></image>
</view>
<view>{{logs.pdate}}</view>

</view>
</view>

<view>{{logs.pcontent}}</view>可以显示出来 为什么image显示不出来？

下面是后台php：<?php
header("Content-Type:application/json;charset=UTF-8");
$uphonenumber = $_POST['phonenumber'];//post获得手机号码表单值

$json = '';
$data = array();
include('init.php');//链接数据库

//$sql = "SELECT * FROM yffice_project where uphonenumber = $uphonenumber";
$sql = "SELECT * FROM yffice_project where uphonenumber = $uphonenumber";
mysql_query("set names utf8");
$result = mysql_query($sql);//执行sql
if($result){
//echo "查询成功";
while ($row = mysql_fetch_array($result))
{
$data["uid"]=$row["uid"];
$data["pcontent"]=$row["pcontent"];
$data["ppic"]=explode(",",$row["ppic"]);
$data["pdate"]=$row["pdate"];
$data["pweek"]=$row["pweek"];
$data["pweather"]=$row["pweather"];
}
$json=json_encode($data);
echo $json;
}else{
echo "查询失败";
}
mysql_close();//关闭数据库

?>

以及php返回的数据：

Answer 1

<view wx:for='{{logs.src}}'>

  <image src="https://yffice.com{{logs.src[index]}}" class="slide-image" />
</view>
这样写就可以了
