I am having trouble using a checkbox to select one or multiple fields of data for PHP/AJAX to process and display. I have the PHP/AJAX working great on my <select>
s but as soon as I try setting up the checkbox all hell breaks lose.
I also am very unsure on how to further prevent SQL injection on the site so if anyone could fill me in a little more about this I would GREATLY appreciate it! I read the link I was provided and just don't understand how bid_param
or PDO works exactly.
The ajax script: (I can't seem to insert the ajax/js so I'll leave a link to the live site)
My php page that displays the data:
<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>
<label for="WorkCity">City</label><br />
<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)">
<?php
include 'datalogin.php';
$result = mysqli_query($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>';
}
?>
</select>

</div>
My php page that pulls the info and places it into a container on the page:
$q = (isset($_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>".$row['First_Name'] . " " .$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>";
}
echo $row['WorkAddress1'] . " " .$row['WorkCity'] . "," . " " .$row['WorkStateProvince'] . " " .$row['WorkZipCode'] . "<br>";
if ($row['Work_Phone'] !== NULL) {
echo "<strong>" . "Work" . " " . "</strong>" .$row['Work_Phone'] . "<br>";
}
if ($row['Fax'] !== NULL) {
echo "<strong>" . "Fax" . " " . "</strong>" .$row['Fax'] . "<br>";
}
echo "<strong>" . "Agent Expertise:" . "</strong>";
if ($row['Ancillary'] == 1) {
echo " " . "Ancillary" . "/";
}
if ($row['SmallGroup'] == 1) {
echo " " . "Small Group" . "/";
}
if ($row['IndividualPlans'] == 1) {
echo " " . "Individual Plans" . "/";
}
if ($row['LongTermCare'] == 1) {
echo " " . "Long Term Care" . "/";
}
if ($row['Medicare'] == 1) {
echo " " . "Medicare" . "/";
}
if ($row['LargeGroup'] == 1) {
echo " " . "LargeGroup" . "/";
}
if ($row['TPASelfInsured'] == 1) {

if ($row['CertifiedForPPACA'] == 1) {

echo "</p>" . "</div>";
}
mysqli_close($con);
?>
I appreciate any and all help on this topic! Any time I add the checkbox values to my php file it ends up displaying everyone in the database for all fields in the form.
I am also trying to prevent sql injection on this but how can a user do this if I don't have a field the user can input text into?
EDIT As of today I gave a try with using jQuery to activate the checkboxes and then call some AJAX. Here is the script I wrote and it is pulling an agent, just not everyone that has that "expertise".
$('input').click(function() {
$.ajax({
url: "process.php",
data: { value: 1},
success: function (data) {
$('#bodyA').html(data);
}
});
});
