我尝试在 PHP 中运行 SELECT
查询,然后选择多行,但我需要将它们提取到数组中,然后使用:echo json_encode($array)
。之后我需要将此数组放入 AJAX 中。
这是 PHP 代码:
$val = $_POST['data1'];
$search = "SELECT * FROM employee WHERE emp_name = :val OR salary = :val OR date_employed = :val";
$insertStmt = $conn->prepare($search);
$insertStmt->bindValue(":val", $val);
$insertStmt->execute();
$insertStmt->fetchAll();
//echo "success";
//$lastid = $conn->lastInsertId();
$i = 0;
foreach($insertStmt as $row)
{
$arr[$i] = $row;
$i++;
}
echo json_encode($arr);
问题是我无法将此数组的所有行放入 AJAX 中,因此我可以将它们附加到某个表中。这是脚本:
var txt = $("#txtSearch").val();
$.ajax({
url: 'search.php', // Sending variable emp, pos, and sal, into this url
type: 'POST', // I will get variable and use them inside my PHP code using $_POST['emp']
data: {
data1: txt
}, //Now we can use $_POST[data1];
dataType: "json", // text or html or json or script
success: function(arr) {
for() {
// Here I don't know how to get the rows and display them in a table
}
},
error:function(arr) {
alert("data not added");
}
});
最佳答案
您需要在成功回调中循环“arr”数据。大致如下:
var txt = $("#txtSearch").val();
$.ajax
({
url: 'search.php', //Sending variable emp, pos, and sal, into this url
type: 'POST', //I will get variable and use them inside my PHP code using $_POST['emp']
data: {data1: txt},//Now we can use $_POST[data1];
dataType: "json", //text or html or json or script
success:function(arr)
{
var my_table = "";
$.each( arr, function( key, row ) {
my_table += "<tr>";
my_table += "<td>"+row['employee_first_name']+"</td>";
my_table += "<td>"+row['employee_last_name']+"</td>";
my_table += "</tr>";
});
my_table = "<table>" + my_table + "</table>";
$(document).append(my_table);
},
error:function(arr)
{
alert("data not added");
}
});
