php mysql基于用户输入表单

我无法使用复选框选择一个或多个数据字段来处理和显示PHP / AJAX。我的<select>上的PHP / AJAX工作得非常好，但是当我尝试设置复选框时，所有地狱都会失败。

我也非常不确定如何进一步阻止网站上的SQL注入，所以如果有人能够更多地了解我，我会非常感激！我阅读了我提供的链接，只是不明白bid_param或PDO是如何工作的。

Link to Agent search page

我的php页面显示数据：

<div id="bodyA">
    <h1>Find a Local OAHU Agent.</h1>
    <!-- This is where the data is placed. -->  
</div>
<div id="sideB">
    <div class="sideHeader">
        <em>Advanced Search</em>            
    </div>
    <form class="formC">
        <label for="last">Last Name</label><br />
        <select id="last" name="Last_Name" onChange="showUser(this.value)">
<?php 
    include 'datalogin.php';

    $result = mysqli_query($con, "SELECT DISTINCT Last_Name FROM `roster` ORDER BY Last_Name ASC;");
    echo '<option value="">' . 'Select an Agent' .'</option>';
    while ($row = mysqli_fetch_array($result)) {
        echo '<option value="'.$row['Last_Name'].'">'.$row['Last_Name'].'</option>';
    }
?>
        </select>
        <label for="company">Company</label><br />
        <select id="company" name="users" onChange="showUser(this.value)">
<?php 
    include 'datalogin.php';

    $result = mysqli_query($con, "SELECT DISTINCT Company FROM `roster` ORDER BY Company ASC;");
echo '<option value="">' . 'Select a Company' .'</option>';
    while ($row = mysqli_fetch_array($result)) {
        if ($row['Company'] == NULL) {
        } else {
            echo '<option value="'.$row['Company'].'">'.$row['Company'].'</option>';
        }
    }

        <select id="WorkCity" name="WorkCity" onChange="showUser(this.value)" value="city">
<?php 
    include 'datalogin.php';

    $result = mysqli_query($con, "SELECT DISTINCT WorkCity FROM `roster` ORDER BY WorkCity ASC;");
    echo '<option value="">' . 'Select a City' .'</option>';
    while ($row = mysqli_fetch_array($result)) {
        echo '<option value="'.$row['WorkCity'].'">'.$row['WorkCity'].'</option>';
    }
?>
        </select>
        <label for="WorkZipCode">Zip Code</label><br />
        <select id="WorkZipCode" name="WorkZipCode" onChange="showUser(this.value)">

      $result = mysqli_query($con, "SELECT DISTINCT WorkZipCode FROM `roster` ORDER BY WorkZipCode + 0 ASC;");
      echo '<option value="">' . 'Select a Zip Code' .'</option>';
      while ($row = mysqli_fetch_array($result)) {
          echo '<option value="'.$row['WorkZipCode'].'">'.$row['WorkZipCode'].'</option>';
      }

    </form>
</div>

我的php页面提取信息并将其放入页面上的容器中：      

    $q = (isset($_GET['q'])) ? $_GET['q'] : false; // Returns results from user input

    include 'datalogin.php'; // PHP File to login credentials

    $sql="SELECT * FROM `roster` WHERE Company = '".$q."' OR Last_Name = '".$q."' OR WorkCity = '".$q."' OR WorkZipCode = '".$q."' ORDER BY Last_Name ASC";

    $result = mysqli_query($con,$sql) // Connects to database or die("Error: ".mysqli_error($con));

    echo "<h1>" . "Find a Local OAHU Agent." . "</h1>";

    while ($row = mysqli_fetch_array($result)) { // Gets results from the database
                echo "<div class='agentcon'>" . "<span class='agentn'>" . "<strong>".$row['First_Name'] . "&nbsp;" .$row['Last_Name'] . "</strong>" . "</span>" . "<a href=mailto:".$row['Email'] . ">" . "<span class='email'>".$row['Email'] . "</span>" . "</a>" ."<div class='floathr'></div>";
                if ($row['Company'] == NULL) {
                    echo "<p>";
                }
                else {
                    echo "<p>" . "<strong>" .$row['Company'] . "</strong>" . "<br>";
                }

                }
                if ($row['Fax'] !== NULL) {
                    echo "<strong>" . "Fax" . "&nbsp;" . "</strong>" .$row['Fax'] . "<br>";
                }

                }

                        echo "&nbsp;" . "Medicare" . "/";
                }

感谢您对此主题的任何帮助！每当我将复选框值添加到我的php文件时，它最终会在数据库中显示表单中所有字段的所有人。

我也试图阻止sql注入，但是如果我没有用户可以输入文本的字段，用户怎么能这样做呢？

EDIT 截至今天，我尝试使用jQuery激活复选框，然后调用一些AJAX。 这是我写的剧本，它正在拉动代理人，而不是每个拥有“专业知识”的人。

$('input').click(function() {
        $.ajax({
            url: "process.php",
            data: { value: 1},
            success: function (data) {
                $('#bodyA').html(data);
            }
        });
    });

这是我最近工作的一个简单示例，其中我需要遍历多个复选框并将这些值传递给SQL语句。虽然这个例子发生在点击按钮上，但希望它与你想要完成的事情有关，或者至少在开始......：）

<?php
$array = array();
if (isset($_POST['medicare'])) {
    foreach ($_POST['medicare'] as $value) {
        array_push($array, $value);
    }
}
// this will return the value of each selected checkbox, separating each with a comma
$result = implode(",", $array);

// if you want to loop through each individually (for example pass each into a SQL statement)
foreach ($_POST['medicare'] as $value) {
    // Do your SQL here 
    // $value will be the value of each selected checkbox (Smallgroup, Largegroup, etc.)
    $sql = "insert into tablename(fieldname) values ('$value')"; // just an example
}
?>

<input type="checkbox" name="medicare[]" id="smallgroup" value="Smallgroup" />
<label for="smallgroup">Small Group</label>
<br />
<input type="checkbox" name="medicare[]" id="largegroup" value="Largegroup" />
<label for="largegroup">Large Group</label>
<br />
<input type="checkbox" name="medicare[]" id="medicare" value="Medicare" />
<label for="medicare">Medicare</label>
<br />
<input type="checkbox" name="medicare[]" id="individualplan" value="IndividualPlan" />
<label for="individualplan">Individual Plan</label>
<br />
<input type="submit" value="Submit" id="btnSubmit" name="btnSubmit" />

<强>更新

尝试为每个select控件设置一个变量，并将SQL语句放在foreach循环中，而不是设置一个变量。我刚用一些虚拟数据对此进行了测试，并且没有任何问题。

<?php
$lastname = (isset($_GET['Last_Name'])) ? $_GET['Last_Name'] : false;
$users = (isset($_GET['users'])) ? $_GET['users'] : false;
$workCity = (isset($_GET['WorkCity'])) ? $_GET['WorkCity'] : false;
$WorkZipCode = (isset($_GET['WorkZipCode'])) ? $_GET['WorkZipCode'] : false;

foreach ($_GET['medicare'] as $value) {
    //echo $value;
    $sql="SELECT * FROM roster WHERE Company = '$users' OR Last_Name = '$lastname' OR WorkCity = '$workCity' OR WorkZipCode = '$WorkZipCode' OR Ancillary = '$value' ORDER BY Last_Name ASC";
}
...continue as you were...
?>

答案 1 :(得分：2)

我知道!! Wohoo！我最后只是创建一个名为expertise.php的独立php页面来使用jquery / ajax处理复选框。

实现这个目标的jQuery :(感谢上帝，我进入jQuery网站查找功能！）

$('input').click(function() {
        $.ajax({
            url: "expertise.php",
            data: { value: 1},
            success: function (data) {
                $('#bodyA').html(data);
            }
        });
    });

除了sql：

之外，PHP页面与我的process.php页面相同 
$sql="SELECT * FROM `roster` WHERE Ancillary = '1' AND SmallGroup = '1' AND CertifiedForPPACA = '1' ORDER BY Last_Name ASC";

如果有人能够更好地启发我，使其更好地防止sql注入，请随意！

Agent Search Page

我至少让搜索的两个部分都工作了但是出现了一个新问题：p

现在在sql中我可以使用AND或OR，使用AND它只会提供拥有这些专业知识且具有OR的代理，它似乎可以吸引所有人。有什么想法吗？
