How to use ajax to receive json data in ThinkPHP, thinkphpjson
The example in this article describes the method of using ajax to receive json data in ThinkPHP. Share it with everyone for your reference. The specific analysis is as follows:
Ajax is implemented here through ThinkPHP+jquery. It is expanded and a query is written. The front-end code is as follows:
First you need to introduce jquery.js, the main code is as follows:
//Since ThinkPHP does not parse ThinkPHP constants in JavaScript, they need to be defined here first.
var URL='__URL__';
$.ajax({
url: URL+'/returnAjax/id/'+id,//Submit the URL for access
type: 'GET', // Submission method
dataType: 'text', //The type of content returned, since the PHP file is echoed directly, then here is text
timeout: 1000, // timeout time
error: function(){ //If an error occurs, execute the function
alert('Error loading XML document');
},
Success: function(data){
//alert(data);//If successful, pop up the data
writeHtml(data,pic);
}
});
}
function writeHtml(data,pic){
var product = eval('(' + data + ')'); //It can be converted into a json object even without introducing json.js
//alert($("#cate_pic").attr("src"));
$("#cate_pic").attr("src","../images/"+pic);
$("#product_pic").attr("src","../Attachments/product/"+product.attachpath+"/"+product.attachthumb);
$("#product_subject").html(product.subject);
$("#product_content").html(product.content);
}
Use echo output in Product.class.php. The json_encode() method in thinkphp can automatically convert the object into json format
$id = $_GET['id'];
$Product=D('Product')->where('id='.$id)->find();
//Return a data set in json format
echo json_encode($Product);
//print_r(json_encode($Product));
}
The returned data format is as follows:
{
"id":"9",
"userid":"1",
"cid":"10",
"cid":"10",
"subject":"1111",
"color":"",
"spec":"",
"size":"",
"keywords":"",
"content":"
1111
","meno":"1111",
"attachpath":"200903",
"attachment":"49d1d86e68d31.png",
"attachthumb":"49d1d86e68d31_thumb.png"
}
I hope this article will be helpful to everyone’s PHP programming based on the ThinkPHP framework.
