在Select HTML中顯示MySQL字段的所有記錄
[英]Show all records of a MySQL field in a Select HTML
問題描述
美好的一天，我正在為大學准備一些小型審計員的預訂系統，一個（01）用戶可以進行幾個預訂，預訂后，用戶必須通過上傳pdf告知付款。
我向用戶顯示一個表格，通過上傳帶有預訂編號和小型審核的pdf通知付款，但是如果我有幾個預訂，則需要顯示所有預訂，以便他選擇所有已付款的預訂，然后選擇我想告知一下，因為我現在的代碼僅向我顯示了第一個保留，並且我希望當我單擊“選擇” HTML時，我將顯示它具有的所有保留編號以及與該保留關聯的小型審核。 然后我離開代碼（我很抱歉，我正在學習，並且我可能有很多錯誤，我也為我的英語不好對不起）：
這是一個現在看起來如何的示例https://i.imgur.com/XvRdRTe.gif
<?php session_start(); include '/login/funcs/funcs.php'; include_once 'config.inc.php'; if(!isset($_SESSION["id_usuario"])){ //Si no ha iniciado sesión redirecciona a index.php header("Location: index.php"); } $idUsuario = $_SESSION['id_usuario']; $db=new Conect_MySql(); $sql2 = "SELECT `idsolicitudes`, `id`, `nombre_sala` FROM solicitudes WHERE `id`=$idUsuario"; $query2 = $db->execute($sql2); $datos=$db->fetch_row($query2); $sql3 = "SELECT `id`, `usuario`, `nombre`, `apellido` FROM usuarios WHERE `id`=$idUsuario"; $query3 = $db->execute($sql3); $datos2=$db->fetch_row($query3); echo $datos['usuario']; ?> <!DOCTYPE html> <!-- To change this license header, choose License Headers in Project Properties.

這是我的連接功能
<?php class Conect_MySql { var $obj = array ( "dbname" => "login", "dbuser" => "root" , "dbpwd" => "" , "dbhost" => "localhost" ); var $q_id =""; var $ExeBit =""; var $db_connect_id = ""; var $query_count = 0; private function connect(){ $this->db_connect_id = mysqli_connect($this->obj['dbhost'],$this->obj['dbuser'],$this->obj['dbpwd'],$this->obj['dbname']); if (!$this->db_connect_id) { echo (" Error no se puede conectar al servidor:".mysqli_connect_error()); } } function execute($query) { $this->q_id = mysqli_query($this->db_connect_id,$query); if(!$this->q_id ) { $error1 = mysqli_error($this->db_connect_id); die ("ERROR: error DB.<br> No Se Puede Ejecutar La Consulta:<br> $query <br>MySql Tipo De Error: $error1"); exit; } $this->query_count++; return $this->q_id; } public function fetch_row($q_id = "") { if ($q_id == "") { $q_id = $this->q_id; } $result = mysqli_fetch_array($q_id); return $result; } public function get_num_rows() { return mysqli_num_rows($this->q_id); } public function get_row_affected(){ return mysqli_affected_rows($this->db_connect_id); } public function get_insert_id() { return mysqli_insert_id($this->db_connect_id); } public function free_result($q_id) { if($q_id == ""){ $q_id = $this->q_id; } mysqli_free_result($q_id); } public function close_db(){ return mysqli_close($this->db_connect_id); } public function more_result() { return mysqli_more_results($this->db_connect_id); } public function next_result() { return mysqli_next_result($this->db_connect_id); } public function __construct(){ $this->connect(); } } ?>

mysqli_fetch_raw($results)
和
mysqli_fetch_array($results)
只會給您有關一種原料的信息。 和使用，
$datos = mysqli_fetch_all($query2)
您可以通過添加for循環來獲取所有輸出結果。 例如。
如果要獲得所有輸出，
<select id="disabledSelect" name="titulo" style="WIDTH: 228px; HEIGHT: 40px" class="form-control">
<?php
for ($i=0 ; $i<=(count($result)-1);$i++){
if ($i==0){$selected="select";} else {$selected=""}
echo '<option value="'. $result[$i][0].'" '.$selected.'>'.$result[$i][2].'</option>';
}
?php
</select>
