[英]PHP Multiple input search
我目前正在使用PHP,並且有3個文本輸入。 在MySQL數據庫中搜索這些值,這些值應返回與輸入的條件相對應的任何數量的結果。
這是搜索表:
<form id='SearchPersonal' method='post' action='businessUsersSearch.php' accept-charset='UTF-8'>
<fieldset >
<legend>Search</legend>
<div class='container'>
<label for='C_Name' >Business Name: </label><br/>
<input type='text' name='C_Name' id='C_Name' maxlength="50" /><br/>
<label for='C_County' >City: </label><br/>
<input type='text' name='C_County' id='C_County' maxlength="50" /><br/>
<label for='Job_Type' >Job Type: </label><br/>
<input type='text' name='Job_Type' id='Job_Type' maxlength="50" /><br/>
</div>
<div class='container'>
<input type='submit' name='Submit' value='Search' />
</div>
</fieldset>
</form>
這也是它在操作中也鏈接的PHP腳本:
<?php
$mysqli_link = mysqli_connect("server", "database", "pass", "user");
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
if(isset($_POST['submit'])) {
// define the list of fields
$fields = array('C_Name', 'C_County', 'Job_Type');
$conditions = array();
// loop through the defined fields
foreach($fields as $field){
// if the field is set and not empty
if(isset($_POST[$field]) && $_POST[$field] != '') {
// create a new condition while escaping the value inputed by the user (SQL Injection)
$conditions[] = "'$field' LIKE '%" . mysqli_real_escape_string($mysqli_link, $_POST[$field]) . "%'";
}
}
// builds the query
$query = "SELECT C_Name, C_StreetNumber, C_StreetName, C_Postcode, C_County, C_Tele, C_Website, Contact_Forename, Contact_Surname, Contact_Email, Jobs.Job_Type, Jobs.Job_Price FROM Company INNER JOIN Jobs ON Company.Company_ID = Jobs.Company_ID";
// if there are conditions defined
if(count($conditions) > 0) {
// append the conditions
$query .= " WHERE " . implode (' AND ', $conditions); // you can change to 'OR', but I suggest to apply the filters cumulative
}
$result = mysqli_query($mysqli_link, $query) or die(mysql_error());
mysqli_close($mysqli_link);
if(isset($_POST['submit'])) {
while($row = mysqli_fetch_assoc($result)) {
$C_Name = $row['C_Name'];
$C_StreetNumber = $row['C_StreetNumber'];
$C_StreetName = $row['C_StreetName'];
$C_Postcode = $row['C_Postcode'];
$C_County = $row['C_County'];
$C_Tele = $row['C_Tele'];
$C_Website = $row['C_Website'];
$Contact_Forename = $row['Contact_Forename'];
$Contact_Surname = $row['Contact_Surname'];
$Contact_Email = $row['Contact_Email'];
$Job_Type = $row['Job_Type'];
$Job_Price = $row['Job_Price'];
echo "<b>Name: $C_Name</b><br>Street Number: $C_StreetNumber<br>Street Name: $C_StreetName<br>Postcode: $C_Postcode<br>County: $C_County<br>Telephone: $C_Tele<br>Website: $C_Website<br>Contact Name: $Contact_Forename $Contact_Surname<br>Email: $Contact_Email<br>Job Type: $Job_Type<br>Job Price: $Job_Price<hr><br>";
}
}
}
?>
由於某種原因,它返回“
文件意外結束
“但是,我檢查了代碼,並在最后添加另一個'}'時正確地關閉了所有代碼(從我所看到的),該腳本根本不返回任何內容。任何人都知道為什么會這樣發生了什么?

因為你忘了關閉
if(isset($_POST['submit'])) {// you not close the condition
在文件末尾
只需在文件末尾添加}
固定:
if(isset($_POST['submit'])) {
// define the list of fields
$fields = array('C_Name', 'C_City', 'Job_Type', 'Review_Rate');
$conditions = array();
}
// builds the query
$query = "SELECT Company.C_Name, Company.C_StreetNumber, C_StreetName, C_Postcode, C_City, C_County, C_Tele, C_Website, Contact_Forename, Contact_Surname, Contact_Email, Job_Type, Job_Price, Review_Rate, Review_Comment

INNER JOIN Jobs ON Company.Company_ID = Jobs.Company_ID
INNER JOIN Review ON Jobs.Job_ID = Review.Job_ID";
// loop through the defined fields

}
}
