这是我的第一个利用服务器端技术的网站.而且,这也是我第一次钻研PHP沿侧工作MYSQL.我一直在工作和学习.
我为一个小型舞会礼服业务的产品条目数据库创建了一个基本管理页面.
我一直在研究表单的功能,管理员可以使用该表单将新条目上传到数据库.
其中一些条目包括:
着装名称[文字输入]
颜色可用性[复选框]
我遇到了从HTML表单中的多个复选框将数据导入数据库的问题.
复选框中的选项应表示布尔值(是/否 - 1/0)
这是表单结构:
<form action="inventory_list.php" enctype="multipart/form-data" name="myForm" id="myform" method="post">
<table width="90%" border="0" cellspacing="0" cellpadding="6">
<tr>
<td width="20%" align="right">Dress Name</td>
<td width="80%"><label>
<input name="Dress_name" type="text" id="Dress_name" size="64" />
</label>
</td>
</tr>
<tr>
<td align="right">Collections</td>
<td>
<label>
<select name="collections" id="collections">
<option value="other">Other</option>
<option value="hermione">Hermione</option>
<option value="jora">Jora</option>
<option value="manon">Manon</option>
</select>
</label></td>
</tr>
<tr>
<td align="right">Available Sizes</td>
<td>
<input type="checkbox" name="sizes[]" value="1" /> Sizes 2-6<br />
<input type="checkbox" name="sizes[]" value="1" /> Sizes 6-10 <br />
<input type="checkbox" name="sizes[]" value="1" /> Sizes 10-14<br />
<input type="checkbox" name="sizes[]" value="1" /> Sizes 14-18 <br />
<input type="checkbox" name="sizes[]" value="1" /> Sizes 18-22<br />
<input type="checkbox" name="sizes[]" value="1" /> Sizes 22-26 <br />
</td>
</tr>
<tr>
<td align="right">Dress Colours</td>
<td>
<input type="checkbox" name="colours[]" value="1" /> Pinks/Reds <br />
<input type="checkbox" name="colours[]" value="1" /> Blues/Greens <br />
<input type="checkbox" name="colours[]" value="1" /> Violet/Purple<br />
<input type="checkbox" name="colours[]" value="1" /> Yellow/Orange/Brown/Gold <br />
<input type="checkbox" name="colours[]" value="1" /> Black/White<br />
</td>
</tr>
<tr>
<td align="right">Product Image</td>
<td><label>
<input type="file" name="fileField" id="fileField" />
</label></td>
</tr>
<tr>
<td> </td>
<td><label>
<input type="submit" name="button" id="button" value="Add This Item Now" />
</label></td>
</tr>
</table>
</form>
这是我为处理向数据库提交数据的表单而构建的PHP.
<?php
if (isset($_POST['Dress_name'])) {
$dress_name = mysql_real_escape_string($_POST['Dress_name']);
$collections = mysql_real_escape_string($_POST['collections']);
$sizesArray = $_POST['sizes'];
$coloursArray = $_POST['colours'];
foreach ($sizesArray as $key => $value)
{
echo "Key = $key || Value = $value<br />";
}
foreach ($coloursArray as $ckey => $cvalue)
{
echo "Key = $ckey || Value = $cvalue<br />";
}
//See if that product name is an identical match to another product in the system
$sql = mysql_query("SELECT ID FROM names WHERE Dress='$dress_name' LIMIT 1");
$productMatch = mysql_num_rows($sql); // count the output amount
if ($productMatch > 0) {
echo 'Sorry you tried to place a duplicate "Product Name" into the system, <a href="inventory_list.php">click here</a>';
exit();
}
//Add this product into the database now
$sql = mysql_query("INSERT INTO names (Dress)
VALUES('$dress_name')") or die (mysql_error());
$pid = mysql_insert_id();
//Place image in the folder
$newname = "$pid.jpg";
move_uploaded_file( $_FILES['fileField']['tmp_name'], "../inventory_images/$newname");
header("location: inventory_list.php");
exit();
}
?>
正如您所看到的,我已将数据放入数组中.而现在我已经碰到了一堵砖墙,我似乎找不到任何有意义的答案.
如何将布尔值获取到数据库表中的正确列？
感谢你的时间!
首先要知道的是,如果选中,HTML复选框将返回结果,如果未选中则将返回任何内容.因此,在html中重要的是增加值:
<td align="right">Available Sizes</td>
<td>
<input type="checkbox" name="sizes[]" value="1" /> Sizes 2-6<br />
<input type="checkbox" name="sizes[]" value="2" /> Sizes 6-10 <br />
<input type="checkbox" name="sizes[]" value="3" /> Sizes 10-14<br />
<input type="checkbox" name="sizes[]" value="4" /> Sizes 14-18 <br />
<input type="checkbox" name="sizes[]" value="5" /> Sizes 18-22<br />
<input type="checkbox" name="sizes[]" value="6" /> Sizes 22-26 <br />
</td>
完全规范化的数据库模式看起来像这样:
//Note that 'names' and 'collections are overloaded
//words and should be avoided
table BRANDS
id INT AUTOINCREMENT
collectionname VARCHAR
table SIZES
id INT AUTOINCREMENT
sizecategory VARCHAR //ie 'Sizes 18-22'
table COLOURS
id INT AUTOINCREMENT
colourname VARCHAR
table INVENTORY
id INT AUTOINCREMENT
brandid INT FOREIGN KEY (BRAND)
imageurl VARCHAR
table INVENTORY_SIZES
inventoryid INT FOREIGN KEY
sizeid FOREIGN KEY
table INVENTORY_COLOURS
inventoryid INT FOREIGN KEY
colourid FOREIGN KEY
你BRAND,COLOURS并SIZES表将需要与您的可用选项正确填充,并且理论上你可以动态地从这些表中的数据加载页面.这些表中每行的ID应最终作为复选框数组中的值.
//get your inputs
$query_values = array();
$query_values[':brandid'] = $dress_name = $_POST['Dress_name'];//note that you should change the value in your options here to the unique ids in your database.
$query_values[':sizeid'] = getSize($_POST[]);
$query_values[':colourid'] = getColour($_POST[]);
$query_values[':quantity'] = $_POST['quantity'];
$query_values[':imageurl'] = $_POST['imageurl'];
//Prepare and execute your sql
//Note that PDO will handle escaping problematic inputs.
$sql = "INSERT INTO INVENTORY ('brandid', 'imageurl') VALUES (:brandid, :sizeid, :colourid, :quantity, :imageurl)";
executeInsert($sql, $query_values);
$inventoryid = mysql_insert_id();
saveSizes($_POST['sizes'], $inventoryid);
saveColours($_POST['colours'], $inventoryid);
function saveSizes($size_array, $inventoryid) {
$sql = "INSERT INTO INVENTORY_SIZES ('inventoryid', 'sizeid') VALUES (:inventoryid, :sizeid)";
foreach ($size_array as $sizeid) {
$query_values = array();
$query_values[':inventoryid'] = $inventoryid;
$query_values[':sizeid'] = $sizeid;
executeInsert($sql, $query_values);
}
}
function saveColours($colour_array) {
$sql = "INSERT INTO INVENTORY_COLOURS ('inventoryid', 'colourid') VALUES (:inventoryid, :colourid)";
foreach ($size_array as $sizeid) {
$query_values = array();
$query_values[':inventoryid'] = $inventoryid;
$query_values[':colourid'] = $colourid;
executeInsert($sql, $query_values);
}
}
function executeInsert($sql, $query_values) {
$query = $conn->prepare($sql);
$query->execute($query_values);
}
请务必使用PHP PDO来防范安全问题.我相当肯定其中一些可以被抽象出来/清理得更好,但这应该可以胜任.(虽然我也很确定,因为我正在做这种感冒而没有进行测试,所以会有一些小错误.)
