Question

那么必须有一种更简单，更自动的方法。我基本上都在为每个单选按钮查询数据库。这一切都有效，但实施更多内容会让我痛苦，有人能给我一些提示吗？

这是我迄今为止所做的。

checkStatus.php

http://localhost/myproject/first

skap.php

    require_once 'connectdb.php';

$skap_NummerID_A1_1 = "A1-1";
$skap_NummerID_A1_2 = "A1-2";
$skap_NummerID_A1_3 = "A1-3";
$skap_NummerID_A1_4 = "A1-4";
$skap_NummerID_A1_5 = "A1-5";

    //THIS IS LOCKER NUMBER A1_1
$displayStatus_query_A1_1 = "SELECT Skap_Nummer, Status FROM testskap WHERE Skap_Nummer ='$skap_NummerID_A1_1'";
$resultStatus_A1_1 = $connect_DB->query($displayStatus_query_A1_1);
if ($resultStatus_A1_1->num_rows > 0) {
    //output data of each row
    while($rowStatus_A1_1 = $resultStatus_A1_1->fetch_assoc()) {
        $skap_sjekkStatus_A1_1 = $rowStatus_A1_1["Status"];
    }}

//THIS IS LOCKER NUMBER A1_2
$displayStatus_query_A1_2 = "SELECT Skap_Nummer, Status FROM testskap WHERE Skap_Nummer ='$skap_NummerID_A1_2'";
$resultStatus_A1_2 = $connect_DB->query($displayStatus_query_A1_2);
if ($resultStatus_A1_2->num_rows > 0) {
    //output data of each row
    while($rowStatus_A1_2 = $resultStatus_A1_2->fetch_assoc()) {
        $skap_sjekkStatus_A1_2 = $rowStatus_A1_2["Status"];
    }}

//THIS IS LOCKER NUMBER A1_3
$displayStatus_query_A1_3 = "SELECT Skap_Nummer, Status FROM testskap WHERE Skap_Nummer ='$skap_NummerID_A1_3'";
$resultStatus_A1_3 = $connect_DB->query($displayStatus_query_A1_3);
if ($resultStatus_A1_3->num_rows > 0) {
    //output data of each row
    while($rowStatus_A1_3 = $resultStatus_A1_3->fetch_assoc()) {
        $skap_sjekkStatus_A1_3 = $rowStatus_A1_3["Status"];
    }}

//THIS IS LOCKER NUMBER A1_4
$displayStatus_query_A1_4 = "SELECT Skap_Nummer, Status FROM testskap WHERE Skap_Nummer ='$skap_NummerID_A1_4'";
$resultStatus_A1_4 = $connect_DB->query($displayStatus_query_A1_4);
if ($resultStatus_A1_4->num_rows > 0) {
    //output data of each row
    while($rowStatus_A1_4 = $resultStatus_A1_4->fetch_assoc()) {
        $skap_sjekkStatus_A1_4 = $rowStatus_A1_4["Status"];
    }}

//THIS IS LOCKER NUMBER A1_5
$displayStatus_query_A1_5 = "SELECT Skap_Nummer, Status FROM testskap WHERE Skap_Nummer ='$skap_NummerID_A1_5'";
$resultStatus_A1_5 = $connect_DB->query($displayStatus_query_A1_5);
if ($resultStatus_A1_5->num_rows > 0) {
    //output data of each row
    while($rowStatus_A1_5 = $resultStatus_A1_5->fetch_assoc()) {
        $skap_sjekkStatus_A1_5 = $rowStatus_A1_5["Status"];
    }}

我喜欢其中的25个，而且我需要做更多，但我想知道有更简单的方法吗？

Answer 1

checkstatus.php

$nummers = array("A1-1", "A1-2", "A1-3", "A1-4", "A1-5");
$output = array();

foreach($nummers as $nummer) {
    $output[$nummer] = array();
    //THIS IS LOCKER NUMBER A1_1
$query = "SELECT Skap_Nummer, Status FROM testskap WHERE Skap_Nummer ='$nummer'";
$result = $connect_DB->query($query);
if ($result->num_rows > 0) {
    //output data of each row
    while($row = $result->fetch_assoc()) {
        $output[$nummer][] = $row["Status"];
    }}
}

skap.php

$nummers = array("A1-1", "A1-2", "A1-3", "A1-4", "A1-5");
foreach($nummer as $nummer) {
    echo '<input type="radio" id="'.$nummer.'" name="radios" value="'.$nummer.'" class="radio-toolbar-all-input" '.($output[$nummer] === "Aktiv") ? "disabled" : "").'>
        <label class="'.($output[$nummer] === "Aktiv") ? $changecsstoo_Aktiv : $changecsstoo_Inaktiv).'" for="'.$nummer.'">'.$nummer.'</label>';
}

你应该从某个配置文件中获取$ nummers数组

是的，每当你发现自己重复这样的代码时，通常需要使用一个简单的循环：

$displayStatusResults = [];

$displayStatusQuery = "SELECT Skap_Nummer, Status FROM testskap WHERE Skap_Nummer IN('A1-1','A1-2','A1-3','A1-4','A1-5')";

$result = $connect_DB->query($displayStatusQuery);

if ($result->num_rows > 0) {
    while($row= $result->fetch_assoc()) {
        $displayStatusResults[$row['Skap_Nummer']] = $row['Status'];
    }
}

skap.php

<div class="row">
<?php $count=0;
 foreach($displayStatusResults as $skap => $status): $count++;?>

    <input 
        type="radio" 
        id="<?=$skap?>" 
        name="radios" 
        value="<?=$skap?>" 
        class="radio-toolbar-all-input" 
        <?= ($status === "Aktiv")? 'disabled':''?>>

    <label 
        class="<?= ($status === "Aktiv")? $changecsstoo_Aktiv : $changecsstoo_Inaktiv?>" 
        for="<?=$skap?>">
        <?=$skap?>
    </label> 

    <?php if($count==8):?>
</div><!--end row--><div class="row">    
    <?php endif; $count=0;?>

<?php endforeach;?>
</div><!--end row-->
