我有一个 PHP 数组，其中有一些相关信息要像这样回显。

<?php 

    $options = array(

        array("name" => "Title",
            "desc" => "Description",
            "type" => '_one',
            "tab-name" => "Tab 1"

        ),

        array("name" => "Title2",
            "desc" => "Description2",
            "type" => '_two',
            "tab-name" => "Tab 2"

        ),

        array("name" => "Title3",
            "desc" => "Description3",
            "type" => '_three',
            "tab-name" => "Tab 3"

        )

    )

?>

我已经创建了一个函数来回显名称、desc，并且运行良好

在这里:

<?php

function create_heading($value) {
    echo '<h2>'.$value['name'].'</h2>';
}
function create_description($value){
    echo '<p>'.$value['desc'].'</p>'
}

function wrapper1($value) {
    echo '<h1>This is the wrapper 1</h1>'
    create_heading($value);
    create_description($value);
}

function wrapper2($value) {
    echo '<h1>This is the wrapper 2</h1>'
    create_heading($value);
    create_description($value);
}

function wrapper2($value) {
    echo '<h1>This is the wrapper 3</h1>'
    create_heading($value);
    create_description($value);
}


function render_things($options) {
    foreach ($options as $value) {
        switch($value['type']) {
            case "one":
                wrapper1($value);
                break;
            case "two":
                wrapper2($value);
            case "three":
                wrapper3($value);
        }
    }
}


render_things();

?>

那么问题是什么:

问题是我如何根据数组中的选项卡名称动态回显选项卡内的这些值意味着我已经给选项卡名称中的第二个数组的值是两个所以它应该在第二个选项卡中打印如果我将它更改为 1 或 3，它应该分别将值打印为 1 或 3。

div.tab {
    overflow: hidden;

    background-color: #f1f1f1;
}

/* Style the buttons inside the tab */
div.tab button {
    background-color: inherit;
    float: left;
    border: none;
    outline: none;
    cursor: pointer;

}

/* Change background color of buttons on hover */

/* Create an active/current tablink class */
div.tab button.active {

<div class="tab">
  <button class="tablinks" onclick="openCity(event, 'tab1')" id="defaultOpen">tab 1</button>
  <button class="tablinks" onclick="openCity(event, 'tab2')">tab 2</button>
  <button class="tablinks" onclick="openCity(event, 'tab3')">Tab 3</button>
</div>

<div id="tab1" class="tabcontent">

<div id="tab3" class="tabcontent">

</div>

<script>
function openCity(evt, cityName) {
    var i, tabcontent, tablinks;
    tabcontent = document.getElementsByClassName("tabcontent");
    for (i = 0; i < tabcontent.length; i++) {
        tabcontent[i].style.display = "none";
    }
    tablinks = document.getElementsByClassName("tablinks");
    for (i = 0; i < tablinks.length; i++) {
        tablinks[i].className = tablinks[i].className.replace(" active", "");
    }
    document.getElementById(cityName).style.display = "block";
    evt.currentTarget.className += " active";
}

// Get the element with id="defaultOpen" and click on it
document.getElementById("defaultOpen").click();
</script>

注意:我不想使用 js 来实现这些信息，所以如果可以使用 PHP，请大家避免使用 js 答案。

最佳答案

您的 php 页面需要像这样:-

<style>
body {font-family: "Lato", sans-serif;}

/* Style the tab */
div.tab {
    overflow: hidden;
    border: 1px solid #ccc;
    background-color: #f1f1f1;
}

/* Style the buttons inside the tab */
div.tab button {
    background-color: inherit;
    float: left;
    border: none;
    outline: none;
    cursor: pointer;
    padding: 14px 16px;
    transition: 0.3s;
    font-size: 17px;
}

/* Change background color of buttons on hover */
div.tab button:hover {
    background-color: #ddd;
}

/* Create an active/current tablink class */
div.tab button.active {
    background-color: #ccc;
}

.tabcontent {
    display: none;
    padding: 6px 12px;
    border: 1px solid #ccc;
    border-top: none;
}
</style>
<?php
  // i assume that your page have this array available
 $options = array(

        array("name" => "Title",
            "desc" => "Description",
            "type" => '_one',
            "tab-name" => "Tab 1"

        ),

        array("name" => "Title2",
            "desc" => "Description2",
            "type" => '_two',
            "tab-name" => "Tab 2"

        ),

        array("name" => "Title3",
            "desc" => "Description3",
            "type" => '_three',
            "tab-name" => "Tab 3"

        )

    );

?>
<div class="tab">
<?php foreach($options as $option){?>
  <button class="tablinks" onclick='openCity(event, "<?php echo str_replace(" ","",$option["tab-name"]);?>")' id="defaultOpen"><?php echo $option['tab-name'];?></button>
<?php } ?>
</div>


<?php foreach ($options as $opti){?>
    <div id="<?php echo str_replace(' ','',$opti['tab-name']);?>" class="tabcontent">
      <?php foreach($opti as $key=>$val){?>
      <h1><?php echo $key;?> : <?php echo $val;?></h1>
      <?php } ?>
    </div>
<?php } ?>
<script>
function openCity(evt, cityName) {
    var i, tabcontent, tablinks;
    tabcontent = document.getElementsByClassName("tabcontent");
    for (i = 0; i < tabcontent.length; i++) {
        tabcontent[i].style.display = "none";
    }
    tablinks = document.getElementsByClassName("tablinks");
    for (i = 0; i < tablinks.length; i++) {
        tablinks[i].className = tablinks[i].className.replace(" active", "");
    }
    document.getElementById(cityName).style.display = "block";
    evt.currentTarget.className += " active";
}

// Get the element with id="defaultOpen" and click on it
document.getElementById("defaultOpen").click();
</script>
