Question

我正在尝试从数据库中检索数据字段并将其存储在下拉框中，以使它们彼此关联，这已经完成，但是当我将它们放入下拉框时，它们会出现，但它们之间没有空格想要分开的话。任何帮助表示赞赏。

<form name="FrmAmend" method="post" action="amenddvd2.php">
Select from the list below<br>
<select name="Film" t[enter link description here][1]itle="Select DVD">
    <option value="" selected disabled>Select DVD</option>
<?php

$result = mysqli_query($con, "SELECT `DVD ID`, `Title`, `Certificate` FROM tbldvd;");
while ($row = mysqli_fetch_assoc($result)) {
    echo "<option value='" . $row['DVD ID'] . $row['Title'] . $row['Certificate'] . "'>" . $row['DVD ID'] . $row['Title'] . $row['Certificate'] . "</option>";

}
?>
</select><br>
<a href="menu.php"</a>Return To Main Menu<br>
<input type="submit" name="Submit" value="Select DVD">
</a>
</form>

Answer 1

在变体之间建立一个空格

echo "<option value='" . $row['DVD ID'] . $row['Title'] . $row['Certificate'] . "'>" . $row['DVD ID'] . ' ' . $row['Title'] . ' ' . $row['Certificate'] . "</option>";

Answer 2

这种方法会更好

    <form name="FrmAmend" method="post" action="amenddvd2.php">
Select from the list below<br>
<select name="Film" t[enter link description here][1]itle="Select DVD">
<option value="" selected disabled>Select DVD</option>
<?php

$result = mysqli_query($con, "SELECT `DVD ID`, `Title`, `Certificate` FROM tbldvd;");
while ($row = mysqli_fetch_assoc($result)) {
?>
    <option value=' <?php echo"$row['DVD ID'] $row['Title'] $row['Certificate']" ?> ' selected disabled>Select DVD</option>
<?php
 }
?>
   </select><br>
<a href="menu.php"</a>Return To Main Menu<br>
<input type="submit" name="Submit" value="Select DVD">
</a>
</form>
