Question

我正在尝试使用JSON编码显示数据库值，但我不知道如何在我在HTML表单中设置的表中显示它。谁知道怎么做？如果你举个例子，我将不胜感激。

这是我的桌子和我的PHP函数。

<?php 

  //--------------------------------------------------------------------------
  // Example php script for fetching data from mysql database
  //--------------------------------------------------------------------------
  $host = "localhost";
  $user = "root";
  $pass = "";

  $databaseName = "silo";
  $tableName = "temp1";

  //--------------------------------------------------------------------------
  // 1) Connect to mysql database
  //--------------------------------------------------------------------------

  $con = mysql_connect($host,$user,$pass);
  $dbs = mysql_select_db($databaseName, $con);

  $tanggal=$_POST['datepicker'];
  $silo=$_POST['silo'];
  //--------------------------------------------------------------------------
  // 2) Query database for data
  //--------------------------------------------------------------------------
  $result = mysql_query("SELECT * FROM $tableName");          //query
  $array = mysql_fetch_row($result);                          //fetch result 

  if($array>0){
    while($row=mysql_fetch_array($result)){

    }   
 }else{
    echo "<li>Tidak ada artikel yang ditemukan <li>";
 }
  //--------------------------------------------------------------------------
  // 3) echo result as json 
  //--------------------------------------------------------------------------
  echo json_encode($array);

?>

Answer 1

您的阵列上不需要json_encode，您可以通过执行$ array ['column name']来访问数组中的每一列。例如，如果您有一个包含用户名和密码的用户表，并且需要获取它们，则执行$array['username']和$array['password']

查看您的代码，似乎您想逐个显示它们：

while($row=mysql_fetch_array($result)){
    echo "<tr> $row['column name'] </tr>";
}

Answer 2

您可以像这样生成<tbody>的HTML。

 if($array>0){
    $tableHTML = "<tbody>";
    while($row=mysql_fetch_array($result)){
        $tableHTML .= "<tr>";
        $i=0;
        foreach ($row as $key=>$val) {
            $tableHTML .= "<td id='td_s".$i."'>".$row[$key]."</td>";
            $i++;
        }
        $tableHTML .= "</tr>";
    }   
    $tableHTML .= "<tbody>";
 }else{
    echo "<li>Tidak ada artikel yang ditemukan <li>";
 }

您会将列附加到每个<td>以创建表格。

<?php
 $tableHTML = "";
 if($array>0){
    $tableHTML .= "<tbody>";
    while($row=mysql_fetch_array($result)){
        $tableHTML .= "<tr>";
        $i=0;
        foreach ($row as $key=>$val) {
            $tableHTML .= "<td id='td_s".$i."'>".$row[$key]."</td>";
            $i++;
        }
        $tableHTML .= "</tr>";
    }   
    $tableHTML .= "<tbody>";
 } else{
    echo "<li>Tidak ada artikel yang ditemukan <li>";
 }

 echo $tableHTML; //echo the HTML of tbody

 ?>
  </table>

Jquery代码

$( document ).ready(function() {
    $('#ok').on('click', function(e) {

      $.ajax({                                      
      url: '../php/termo_sel.php',                           
      data: {datepicker: 'val1', silo : 'val2'}, //Pass data to PHP by POST
      type: 'post',                       
      dataType: 'json',                     
      success: function(data)    //Whatever is put in echo in PHP is returned here     
      {
        $('#table_s').append(data);
      }
      });

    });
});

只需使用此代码即可。我希望它有所帮助。

这就是我的意思..我的桌子的tbody有一个记录的值。我可以将您编辑过的脚本的回声再次置于其中吗？或者我可以将回声置于jquery中吗？
