I have a custom search function on my site, using PHP. I don't like having to go to my database every time I make a page, so can I write something to automatically add a new page to my database? Here's my code:
<?php
$k = $_GET['k'];
$terms = explode(" ", $k);
$query = "SELECT * FROM search WHERE ";
foreach ($terms as $each){
$i++;
if ($i == 1)
$query .= "keywords LIKE '%$each%' ";
else
$query .= "OR keywords LIKE '%$each%' ";
}
//connect
mysql_connect("*****", "*****", "*****");
mysql_select_db("*****");
$query = mysql_query($query);
$numrows = mysql_num_rows($query);
if ($numrows > 0){
while ($row = mysql_fetch_assoc($query)){
$id = $row['id'];
$title = $row['title'];
$description = $row['description'];
$keywords = $row['keywords'];
$link = $row['link'];
echo "<h3><a href='$link'>$title</a></h3>
<hr />";
}
}
else
echo "No Results Found for \"<b>$k</b>\". Try Again.";
//disconnect
mysql_close();
?>

I'm connected to phpmyadmin but I can not get any data from phpmyadmin.
my php version is 7.2.9 , I made everything that I wanted in database but php can't show the data in site ( I'm using localhost ).
here is the code:
<?php
$key = $_GET['key'];
$terms = explode(" ", $key);
$query = "SELECT * FORM search WHERE ";
foreach ($terms as $each){
$i++;
if($i == 1){
$query .= "keywords LIKE '%$each%' ";
} else{
$query .= "OR keywords LIKE '%$each%' ";
}
echo $query;
}
//connection
mysql_connect("localhost", "root", "");
mysql_select_db('search');
$query = mysqli_query($query);
$numrows = mysqli_num_rows($query);
if($numrows > 0){
while ($row = mysql_fetch_assoc($query)){
$id = $row['id'];
$title = $row['title'];
$description = $row['description'];
$keywords = $row['keywords'];
$link = $row['link'];
echo "<h2><a href='$link'>$title</h2></a>
$description<br /><br />";
}
}
else{
echo "No results found for \"<b>$key</b>\""; }
//disconnect
mysql_close();
?>
You have a couple of mistakes in your PHP/HTML. I'm gonna sum them up here so you can take a look at them:
<h2><a href='$link'>$title</h2></a>$description<br /><br /> This is wrong HTML. Close your a tag inside the h2.
You are connecting to you database through mysql, but querying through mysqli. Connect to your database with mysqli. Mysql_ family of functions have been removed in PHP 7
You have a typo in your query. you have written FORM instead of FROM.
You are exploding your $_GET variable on spaces. But i doubt if a $_GET variable has any spaces to begin with... Check if this is true.
first of all mysql_connect() is not anymore available after php 5. Instead of using mysql use mysqli_connect(). Please how to make connection and query database using php7 here.

If still you have problem. Ask for help in comments.
<?php
$query = "SELECT * FORM search WHERE ";
foreach ($terms as $each){
$i++;
if($i == 1){
$query .= "keywords LIKE '%$each%' ";
} else{
$query .= "OR keywords LIKE '%$each%' ";
}
echo $query;
}
//connection
$conn = mysqli_connect("localhost", "root", "","search");
if(!$conn)die("Connection Error");
$query = mysqli_query($conn,$query);
if(!query)die("query error");
$numrows = mysqli_num_rows($query);
if($numrows > 0){
while ($row = mysqli_fetch_assoc($query)){
$id = $row['id'];
$title = $row['title'];
$description = $row['description'];
$keywords = $row['keywords'];
$link = $row['link'];
echo "<h2><a href='$link'>$title</h2></a>
$description<br /><br />";

You are mixing up mysqli and mysql. I have edited your stuff. Please try. Don't forget to fix the portion marked [missing]
<?php
$key = $_GET['key'];
$terms = explode(" ", $key);
foreach ($terms as $each){
$i++;
if($i == 1){
$query .= "keywords LIKE '%$each%' ";
} else{
$query .= " description OR keywords LIKE '%$each%' ";
}
echo $query;
}
//connection
$conn=mysqli_connect("localhost", "root", "");
mysqli_select_db($conn, 'search');
if($result= mysqli_query($conn, $query)){
$numrows = mysqli_num_rows($result);
}
if($numrows > 0){
while($row = mysqli_fetch_array($result)){
$id = $row['id'];
$title = $row['title'];
$description = $row['description'];
$keywords = $row['keywords'];
$link = $row['link'];
//echo "<h2><a href='$link'>$title</h2></a>
//$description<br /><br />";
echo '<h2><a href="' . $link . '">' . $title .
'</h2></a>' . $description . '<br /><br />';
}
}
else{
echo "No results found for \"<b>$key</b>\""; }
//disconnect
mysqli_close();
?>
Here's the Full working Example TESTED at my end (Last night I wasn't at my work machine and couldn't test the code.Later I created a small db and Tested it. I had searched with the dummy key 'ram mary albert' in my example
<?php
$key = $_GET['key'];
$terms = explode(" ", $key);
$qu1 = "SELECT * FROM search WHERE ";
$qu2 = "order by id ASC";
$conn=mysqli_connect("localhost", "root", "");
mysqli_select_db($conn, 'search');
for($i=0; $i< count($terms); $i++){
$query = $qu1 . " keywords LIKE '%$terms[$i]%' " . $qu2;
echo( $query . "<br>" );
$resulter= mysqli_query($conn, $query);
while($row = mysqli_fetch_array($resulter)){;
$id = $row['id'];
$title = $row['title'];
$description = $row['description'];
$keywords = $row['keywords'];
$link = $row['link'];
$EscLink='\'' . $link . '\'';
echo ('<a href="javascript:void(0)" onClick="alert(' .
$EscLink . ')">' . $title . '</a><br>' . $description .
'<br /><br />');
} // Close While
} // Close for
//disconnect
mysqli_close($conn);

I have created a search box that searches my website. I have tried really hard to fix it but it didn't work. Please could you help? The code is below:
<?php
$k = $_GET['k'];
$terms = explode(" ", $k);
$query = "SELECT * FROM search WHERE "
for each ($terms as $each) {
$i++;
if ($i == 1)
$query .= "keywords LIKE '%$each%' ";
else
$query .= "OR keywords LIKE '%$each%' ";
}
//connect
mysql_connect("localhost", "my username", "my password");
mysql_select_db("my database");
$query = mysql_query($query);
$numrows = mysql_num_rows($query);
if ($numrows > 0){
while ( $row = mysql_fetch_assoc($query)) {
$id = $row['id'];
$title = $row['title'];
$description = $row['description'];
$keywords = $row['keywords'];
$link = $row['link'];
echo "<h1><a href='$link'>$title</a></h2>";
$description<br /><br />""
}
}
else
echo "No results found for \"<b>$k/b>\" ";
//disconnect
mysql_close();
?>
first of all, correct syntax. Instead of:
$query = "SELECT * FROM search WHERE "
for each ($terms as $each) {
should be
$query = "SELECT * FROM search WHERE ";
foreach ($terms as $each) {
and OUH, what's this???
$description<br /><br />""
maybe youd learn the basics of syntax at first.
I created a website search bar using php with mysql, my results page shows all old queries. I even tried from other computers and search queries still appear. I do not have duplicate keywords so that should not be an issue. How can I get the results page to dump old queries?
<?php
$input = $_GET['input'];//Note to self $input in the name of the search feild
$terms = explode(" ", $input);
$query = "SELECT * FROM search WHERE ";
foreach ($terms as $each){
$i++;
if ($i == 1)
$query .= "keywords LIKE '%$each%' ";
else
$query .= "OR keywords LIKE '%$each%' ";
}
// connecting to our mysql database
mysql_connect("localhost", "pti_user", "policetech1");
mysql_select_db("pti_db");
$query = mysql_query($query);
$numrows = mysql_num_rows($query);
if ($numrows > 0){
while ($row = mysql_fetch_assoc($query)){
$id = $row['id'];
$title = $row['title'];
$description = $row['description'];
$keywords = $row['keywords'];
$link = $row['link'];
echo "<h2><a href='$link'>$title</a></h2>
$description<br /><br />";
}
}
else
echo "No results found for \"<b>$input</b>\"";
// disconnect
mysql_close();
?>
<?php
$k = $_GET['K'];
$terms = explode(" ", $k);
$query = "SELECT * FROM search WHERE ";
foreach ( $terms as $each) {
$i++;
if($i == 1)
$query .= "keywords LIKE '%$each%' ";
else
$query .= "OR keywords LIKE '%$each%' ";
}
require("connect.php");
$query = mysql_query($query);
$numrows = mysql_num_rows($query);
if($numrows > 0){
while ($rows = mysql_fetch_assoc($query)){
$id = $rows['id'];
$title = $rows['title'];
$description = $rows['descriptions'];
$keywords = $rows['keywords'];
$link = $rows['link'];
echo "<h2><a href = '$link'> $title </a></h2>
$description <br /> <br />";
}
}else
echo "No results found for \"$k\"";
mysql_close();
You can do like this
$query = "SELECT DISTINCT *FROM search WHERE ";
When i would search for the keywords that i have specified in my database it will return everything from my database not just the corresponding links that have the keywords attached to the link. here is my code
<?php
$q = $_GET['q'];
$terms = explode(" ", $q);
$query = "SELECT * FROM search ";
foreach ($terms as $each){
$i=0;
$i++;
if ($i == 1)
$query .= "keywords LIKE '%$each%' ";
else
$query .= "OR keywords LIKE '%$each%' ";
}
//connect
mysql_connect("localhost", "root", "");
mysql_select_db("search");
$query = mysql_query("SELECT * FROM search");
$numrows = mysql_num_rows($query);
if ($numrows > 0){
while($row = mysql_fetch_assoc($query)){
$id = $row['id'];
$title = $row['title'];
$description = $row['description'];
$keywords = $row['keywords'];
$link = $row['link'];
echo "<h3><a href='$link'>$title</a></h3><h4>$link</h4>$description<br /><br />";
}
}
else
echo "<b>No Results Found</b><br><br>Suggestions:<br>
Make sure all words are spelled correctly.<br>
Try different keywords.<br>
Try more general keywords.";
//disconnect
mysql_close();
?>
<?php
$q = $_GET['q'];
$terms = explode(" ", $q);
//connect
mysql_connect("localhost", "root", "");
mysql_select_db("search");
$query = "SELECT * FROM search ";
$i=1;
foreach ($terms as $each){
if ($i == 1) {
$query .= "WHERE ";
$query .= "keywords LIKE '" . mysql_real_escape_string("%" . $each . "%") . "' ";
} else {
$query .= "OR keywords LIKE '" . mysql_real_escape_string("%" . $each . "%") . "' ";
}
$i++;
}
$query = mysql_query($query);
$numrows = mysql_num_rows($query);
if ($numrows > 0){
while($row = mysql_fetch_assoc($query)){
$id = $row['id'];
$title = $row['title'];
$description = $row['description'];
$keywords = $row['keywords'];
$link = $row['link'];
echo "<h3><a href='$link'>$title</a></h3><h4>$link</h4>$description<br /><br />";
}
} else {
echo "<b>No Results Found</b><br><br>Suggestions:<br>
Make sure all words are spelled correctly.<br>
Try different keywords.<br>
Try more general keywords.";
}
//disconnect
mysql_close();
?>
Fixes:
1) Removed second $query that was being defined. It selected all rows.
2) Moved initial $i declaration. It was being set back to 0 each loop.
3) Added WHERE
4) Moved $i++ after the if statement and set initial $i to 1.
5) Added mysql_real_escape_string so that data is escaped properly.
Recommendations:
I highly recommend taking a look at MySQLi (http://us2.php.net/mysqli) or PDO (http://us3.php.net/pdo)
Please let me know if this works or if you need further assistance.
A first sight, i see a couple of errors.
$i=0;
$i++;
if ($i == 1)
$i Will ALWAYS be one are.
you might want to move $i = 0; BEFORE the foreach
$query = mysql_query("SELECT * FROM search");
You build a query, but in the end you're not using it. you probably want to do : $query = mysql_query($query); instead. ( and also for code clarity using a different variable name for the output ? ) .
mysql_query is deprecated. Useless you're in a hurry, check PDO
First, you're missing the WHERE keyword before the conditions. So it should be:
foreach ($terms as $i => $each){
$each = mysql_real_escape_string($each); // Prevent SQL injection
if ($i == 0)
$query .= "WHERE keywords LIKE '%$each%' ";
else
$query .= "OR keywords LIKE '%$each%' ";
}
You don't need to increment your own counter variable, you can use the array indexes from $terms.
Second, after all that work to create $query, you're not using it. You wrote:
$query = mysql_query("SELECT * FROM search");
That should be:
$query = mysql_query($query);
BTW, it's generally a bad idea to reuse variables like that, it gets confusing when you use the same variable for different things. I suggest you call the second $query something like $results.
Change this line
$query .= "keywords LIKE '%$each%' ";
By
$query .= " Where keywords LIKE '%$each%' ";
And also cnhange this line
$query = mysql_query("SELECT * FROM search");
By
$query = mysql_query($query);
