[英]PHP Increment in For-each Works on Buttons Labels but not on Posted URL
我正在創建一個從網站目錄中讀取和顯示文件的網頁,我使用了for-each循環來遍歷文件並根據增量指定具體名稱。 當用戶單擊特定按鈕時,我將不希望表單傳遞特定增量,因此我知道在轉到下一頁時要使用哪個文件。 按鈕顯示了預期的增量,但是url始終將值傳遞為“ 1”,我真的不知道為什么,我附上了一張圖片以顯示按鈕的作用 但是鏈接始終變為http://Mywebsite.com/AuthorizeCapabilityRequest.php?1
<?php
$images = glob($directory . "*.*");
echo "<div class='col-md-12' align='center'><div class='col-md-10'>
<table class='table table-bordered table-striped'>
<tr>
<th width='65%'>Filename</th>
<th width='20%'>Edit</th>
<th width='15%'>Refer</th>
</tr>";
$dir = "Capability_Request/*";
$zed = 1;
foreach(glob($dir) as $file)
{
$base = basename($file);
echo "<tr><td>";
if(!is_dir($file)) { echo basename($file);}
echo "</td><td><button type='button' class='btn btn-primary btn-
small' data-toggle='modal' data-target='#exampleModal$zed'>
$zed
</button> </td><td>
<!-- Button trigger modal -->
<button type='button' class='btn btn-primary' data-toggle='modal'
data-target='#exampleModalCenter'>
$zed
</button>
<!-- Modal -->
<div class='modal fade' id='exampleModalCenter' tabindex='-1'
role='dialog' aria-labelledby='exampleModalCenterTitle' aria-
hidden='true'>
<div class='modal-dialog modal-dialog-centered' role='document'>
<div class='modal-content'>
<div class='modal-header'>
<h5 class='modal-title' id='exampleModalLongTitle'>Refer
Capability to UNF</h5>
<button type='button' class='close' data-dismiss='modal'
aria-label='Close'>
<span aria-hidden='true'>×</span>
</button>
</div>
<div class='modal-body'>";
$url = "AuthorizeCapabilityRequest.php?".$zed;
echo "<form action='$url' method='post'>";
echo "<h6>If you would like to refer the capability to the
UNF, and accept the capability request, select this
button:</h6>";
echo "<input class='btn btn-success btn-block' type='submit'
value='Submit'>";
echo "<hr>";
echo "<h6>If you would like to refer the capability to the
UNF, but deny the capability request, select this
button:</h6>";
echo "<button type='button' class='btn btn-warning btn-
block'>Refer</button>";
echo "<hr>";
echo "<h6>If you would like to deny the capability referral
to the UNF, select this button:</h6>";
echo "<button type='button' class='btn btn-danger btn-
block'>Deny</button>";
echo "<div class='modal-footer'>";
echo "<button type='button' class='btn btn-secondary' data-
dismiss='modal'>Cancel</button>";
echo "</form>";
echo "</div>";
echo "</div>";
echo "</div>";
echo "</div>";
echo "</td></tr>";
$zed++;
}
echo "</table></div></div>";
元素的ID必須是唯一的。 目前,您為“模態div”的每次迭代賦予相同的ID
<div class='modal fade' id='exampleModalCenter' tabindex='-1'
role='dialog' aria-labelledby='exampleModalCenterTitle' aria-hidden='true'>
因此,您應該做的是幾件事:確保ID都是唯一的(使用$zed
變量),然后使data-target
與該唯一的ID對應(再次使用$zed
變量)。
編輯:這是一個如何工作的示例:
<button type="button" data-toggle="modal" data-target="#exampleModal<?php echo $zed; ?>">
your button
</button>
<div class="modal" id="exampleModal<?php echo $zed; ?>">
your modal
</div>
