我如何将结果从控制台日志保存到数据库？

Question

I have a completed selection and then there is a table that I fill out as well, then by clicking on the button the selected result goes to the console, but how to save it to the database? Please help me, I really need your help PS Ajax request is not needed

 function submit() {
    $table.find('tr').each(function(){
        var rowValues = {};
        $(this).find('td').each(function(i) {
            var value = $(this).find("input").val();
            rowValues[columnNames[i]] = value;
        });
        arr.push(rowValues);
    });

    console.log(arr);

    var selector = document.getElementById('category_select');
    var id = selector[selector.selectedIndex].id;
    console.log(id);

    var selector = document.getElementById('patient_select');
    var value = selector[selector.selectedIndex].value;
    console.log(value);  //How i can save result in db ?
  $.ajax({
            url: 'insert.php',
            type: 'POST',
            data: {
                data: value,
            },
            dataType: 'json',
            beforeSend: function(xhr) {
                $('#bt').text('OK');
            },
            success: function(data) {
                $('#bt').text('Send');
                alert(data);
            }
        });
}

my insert.php

  <?php 

        $value = $_POST['value'];

        $link = mysqli_connect(
            'localhost', 
            'root',       
            '',   
            'answer_result');     
        if (!$link) {
            printf("ERR: %s\n", mysqli_connect_error());
        }

        mysqli_query($link,"INSERT INTO answer_result_table (`answer_content`, `patient_id`)
        VALUES ( '$value', '$value')") 
        or die(mysqli_error($link));
            ?>

Answer 1

I don't know what you mean with Ajax request is not needed .

But I think, that you have to pass that value with AJAX to the Server and let some PHP handle the storage.

Answer 2

恕我直言，最好的选择是：您必须将php代码移动到单独的文件中，并通过ajax进行调用，在请求有效负载中，您必须将json编码的arr和其他所需的数据放置在POST字段中，或者将一个JSON与所有数据一起放置，那么您必须在php json_decode()有效负载中，最后将其保存到数据库

Answer 3

First you need to know that Javascript (at least in this case) is a client side language, and php server side language.

that's mean, according your code, when the browser request this page, the server runs php and then send to the browser the page with the javascript, that will be executed by the browser itself, and the result of php execution (in this case opens a connection and insert a empty record.)

You can run the js script, print the log to the console, and then send the log to another page where the php code will be executed. You can do it in sync mode, like a normal redirect, o in async mode, using AJAX.
