假设我有一个由PHP生成的目录页面。每行数据来自数据库。单击按钮时如何获取表列数据
echo "<form action=\"reservation.php\" method=\"post\">";
for ($i=0; $i <$num_results; $i++) {
$row = $result->fetch_assoc();
if (stripslashes($row['gymid']) == !0) {
echo "<tr>". PHP_EOL;
echo "<td>".stripslashes($i+1)."</td>". PHP_EOL;
echo "<td align=\"center\">".stripslashes($row['gymname'])."</td>". PHP_EOL;
echo "<td>".stripslashes($row['address'])."</td>". PHP_EOL;
echo "<td align=\"center\">".stripslashes($row['location'])."</td>". PHP_EOL;
echo "<td align=\"center\">".stripslashes($row['operatinghours'])."</td>". PHP_EOL;
echo "<td align=\"center\"><input type= \"submit\" id =\"gym".stripslashes($row['gymid'])."\" value=\"BOOK NOW\" class=\"bookbutton\" onClick=\"reply_click(this.id)\"</td>". PHP_EOL;
//echo "<td align=\"center\"><input type=\"submit\" name=\"gyminfo\" class=\"bookbutton\" value=\"".stripslashes($row['gymid'])."\" >BOOK NOW! </td>". PHP_EOL;
echo "</tr>". PHP_EOL;
}
}
echo "</form>";
所以我有一个“立即预订”按钮,每行有独特的id(gymxxxx)。点击该按钮后,该页面将重定向到reservation.php,其中有几个带有健身房名称,位置,时隙等的下拉框。 以下是gymname下拉框:
<label>Gym Name: </label>
<form id="gymInfoForm" method = "post" action = "reservation.php">
<select name="gymSelect"onchange="if (this.selectedIndex) formSubmit();">
<?php
$data = $_POST['gymSelect'];
echo "Data = " . $data;
$query = "SELECT * FROM gymname";
$result = $db->query($query);
$resultNum = $result->num_rows;
echo '<option value="NULL" >Please choose a gym</option>';
for($i = 0; $i < $resultNum; $i++)
{
$row = $result->fetch_assoc();
if($data == $row['gymname'])
{
echo '<option value="' . $row['gymname'] . '" selected>' . $row['gymname'] . '</option>'.PHP_EOL;
}
else
{
echo '<option value="' . $row['gymname'] . '" >' . $row['gymname'] . '</option>'.PHP_EOL;
}
}
?>
</select>
</div>
<div style="margin-bottom:10px">
我的问题是,我怎么能张贴链接到“立即预订”按钮,将reservation.php数据(gymname和位置),这样的选项“gymname”和“location”将被预先选中?
谢谢!
