问题描述
我正在尝试从PHP CodeIgniter中的控制器发送数据以进行查看。
我正在通过 ajax
并使用<$ c来调用PHP函数$ c> ob_flush 发送回数据,但问题是所有刷新调用在以后的调用中被串联。
I am trying to send data to view from controller in PHP CodeIgniter.
I am calling the PHP function through ajax
and using ob_flush
to send data back but the problem is that all the flush calls are concatenated in later calls.
例如:第一次刷新发送 1
第二次刷新调用发送 12
而不是 2
。
For example: the first flush send 1
second flush call send 12
instead of 2
.
这是我的控制器循环。
foreach ($csv_array as $row) {
ob_start();
$varint=$varint+1;
echo $varint;
$content = ob_get_contents();
ob_end_clean();
echo $content;
ob_flush();
flush();
while (ob_get_level() > 0) {
ob_end_clean();
}
}
我的ajax调用是这样:
My ajax call is this:
document.getElementById('upld').onclick = function() {
xhr = new XMLHttpRequest();
var mydata = new FormData($('#form')[0]);
xhr.open("POST", base_url+"index.php/controller/function", true);
xhr.onprogress = function(e) {
console.log(e.currentTarget.responseText);
}
xhr.onreadystatechange = function(data='') {
if (xhr.readyState == 4) {
console.log(myArr);
}
}
xhr.send(mydata);
};
推荐答案
说:
您可以将 flush()
替换为,因为我不认为您要刷新系统输出缓冲区。
In your case you can replace flush()
with ob_flush()
as I don't think you are looking to flush the system output buffers.
作为此代码的补充:
$content = ob_get_contents();
ob_end_clean();
可以压缩为一个函数调用,该函数调用是前面两个命令的组合的别名:
Can be condensed into one function call that is an alias for both of the previous commands combined:
$content = ob_get_clean();
