My query not return any value.
$minprice = itemDetails("SELECT MIN(extra_night) FROM hotel_room WHERE hotel_id ='".$row[hotel_id]."'");
Below is my site

<?php

echo '</div>';
echo '</div>';
echo '<div class="clear">';
}
} else{
echo '<div class="alert-msg error">No record. Please search again.</div>';
}
?>
Supposed to be the $minprice will return the value form my database. Any idea?
The output should shown MYR (value from database),Example: MYR 1200
function itemDetails($query){
$sql_query = mysql_query($query);
$item = mysql_fetch_array($sql_query);
return stripslashes($item[0]);
}

Im creating a basic website that will show 10 different tv programmes.
I have the 10 different programmes stored in the database. Im able to retriev the 10 programmes but they all appear in a column.
I was wondering if theres a way to have then appear 5 in a row?
I have tried basic CSS but i cant seem to get it working
Here is the code i have so far:
<?php
$results = $mysqli->query("SELECT * FROM programmes ORDER BY ProgrammeName ASC");
if ($results) {
while($obj = $results->fetch_object())
{
echo '<br>';
echo '<div class="tvProgs">';
echo '<form method="post" id = "books" action="cart_update.php">';
echo '<div class="progImage"><img src="images/'.$obj->Image.'"></div>';
echo '<div class="progTitle"><h3>'.$obj->ProgrammeName.'</h3>';
echo '</form>';
echo '</div>';
}
}
?>
I was wondering if theres a way to achive that i want or will i have to try something else?
anything will help.
Thanks!
Try to put them in a table:
<?php
$results = $mysqli->query("SELECT * FROM programmes ORDER BY ProgrammeName ASC");
if ($results) {
$i=0;
echo '<table><tr>';
while($obj = $results->fetch_object())
{
echo '<td>';
echo '<div class="tvProgs">';
echo '<form method="post" id = "books" action="cart_update.php">';
echo '<div class="progImage"><img src="images/'.$obj->Image.'"></div>';
echo '<div class="progTitle"><h3>'.$obj->ProgrammeName.'</h3>';
echo '</form>';
echo '</div>';
echo '</td>';
$i++;
if ($i == 5) {
echo '</tr><tr>';
}
}
echo '</tr></table>';
}
?>
You can start from:
$i=0;
echo '<br>';
while($obj = $results->fetch_object())
{
echo '<div class="tvProgs">';
echo '<form method="post" id = "books" action="cart_update.php">';
echo '<div class="progImage"><img src="images/'.$obj->Image.'"></div>';
echo '<div class="progTitle"><h3>'.$obj->ProgrammeName.'</h3>';
echo '</form>';
echo '</div>';
if (($i++) == 5) { echo '<br>'; $i=0; }
}
UPDATE CSS
.tvProgs {
float:left;
width:200px;
display:block;
}
This will put them in a table 5 in each row just like you asked for.
<?php
$results = $mysqli->query("SELECT * FROM programmes ORDER BY ProgrammeName ASC");
if ($results) {
$i = 0;
echo '<table>';
while($obj = $results->fetch_object())
{
if ($i == 0) {
echo '<tr>';
}
echo '<td>';
echo '<div class="tvProgs">';
echo '<form method="post" id = "books" action="cart_update.php">';
echo '<div class="progImage"><img src="images/'.$obj->Image.'"></div>';
echo '<div class="progTitle"><h3>'.$obj->ProgrammeName.'</h3>';
echo '</form>';
echo '</div>';
echo '</tr>';
$i++;
if ($i == 5) {
echo '</tr>';
$i = 0;
}
}
if ($i != 0) {
echo '</tr>';
}
echo '</table>';
}
?>
how do i delete a single record in database? i tried with Ajax and it didn't work.here is my code,each row has a unique number ID,so i need that to delet it,but i don't know how to get it.

I had retrieve some result from database and want to display the result separately.
If the pb_title is same as temp_title then put it togather in a red color div
else is pb_title is not same as temp_title then put it in grey color div
Here my tried code :
$select_brand = "SELECT * FROM tblProduct_Brand WHERE pb_display='display'";
$result = mysqli_query ($mydatabase, $select_brand);
if($result)
{
while($row = mysqli_fetch_array($result))
{
$pb_feature_image = substr(($row['pb_feature_image']),3);
$pb_logo = substr(($row['pb_logo']),3);
$temp_result;
if($temp_result == $row["pb_title"])
{
//if product brand title is same, put it in same area
echo '<div style="padding:20px; background-color:red;">';
echo '<div style="display:inline-block;width:340px;height:250px;vertical-align:top;">';
echo '<img src="'.$pb_feature_image.'" width="100%" height="100%"/>';
echo '</div>';
echo '<div style="display:inline-block;width:330px;height:250px;padding-left:10px;">';
echo '<div style="height:40px;width:80px;float:right">';
echo '<img src="'.$pb_logo.'" width="100%"/>';
echo '</div>';
echo '<div style="clear:both"></div>';
echo '<a class="product-content">'.$row["pb_content"].'</a>';
echo '</div>';
echo '</div>';
$temp_result = $row["pb_title"];
}
else
{
//if not same, put in another area
echo '<div style="padding:20px; background-color:grey;">';
echo '<div style="display:inline-block;width:340px;height:250px;vertical-align:top;">';
echo '<img src="'.$pb_feature_image.'" width="100%" height="100%"/>';
echo '</div>';
echo '<div style="display:inline-block;width:330px;height:250px;padding-left:10px;">';
echo '<div style="height:40px;width:80px;float:right">';
echo '<img src="'.$pb_logo.'" width="100%"/>';
echo '</div>';
echo '<div style="clear:both"></div>';
echo '<a class="product-content">'.$row["pb_content"].'</a>';
echo '</div>';
echo '</div>';
}
}
Any mistake about the code please correct me.
Thanks.
The following code assumes that you did something like this with the data you fetched from the sql query:
$data = array();
while($row = mysqli_fetch_assoc($result)) {
$data[] = $row;
}
Which returns an array like this:
Array (
[0] => Array(
'pb_title' => '',
'pb_content' => '',
//...etc
),
//.....etc
)
Now assuming that I understand your question correctly, you'd want to do something like this:
$i = array();
$key = 'A';
foreach ($data as $item) {
if ($item['pb_title'] == $key) {
$i['red'][] = $item;
} else {
$i['grey'][] = $item;
}
}
Which gives you an array of red (Matching) and grey (Not Matching).
Which you can loop through and generate your div's appropriately.
Something like this (pseudo code)
echo '<div style="padding:20px; background-color:red;">';
foreach($i['red'] as $row) {
echo '<div style="display:inline-block;width:340px;height:250px;vertical-align:top;">';
echo '<img src="'.$pb_feature_image.'" width="100%" height="100%"/>';
echo '</div>';
echo '<div style="display:inline-block;width:330px;height:250px;padding-left:10px;">';
echo '<div style="height:40px;width:80px;float:right">';
echo '<img src="'.$logo.'" width="100%"/>';
echo '</div>';
echo '<div style="clear:both"></div>';
echo '<a class="product-content">'.$row["pb_content"].'</a>';
echo '</div>';
}
echo '</div>';
Example
$temp_result;
if($temp_result == $row["pb_title"])
Before checking the condition you should have assigned some value to $temp_result , but you haven't and you are comparing it anyway.
EDIT :
What I understand is that initially you have not set any value of $temp_result and it is always coming in your Else Block where you do'not assign $temp_result = $row["pb_title"]; , So that it shoudl store the previous value , you only did it in the If Block , you need to place the same code in your else block too..
Simple Edit this section in your code
else
{
//if not same, put in another area
echo '<div style="padding:20px; background-color:grey;">';
echo '<div style="display:inline-block;width:340px;height:250px;vertical-align:top;">';
echo '<img src="'.$pb_feature_image.'" width="100%" height="100%"/>';
echo '</div>';
echo '<div style="display:inline-block;width:330px;height:250px;padding-left:10px;">';
echo '<div style="height:40px;width:80px;float:right">';
echo '<img src="'.$pb_logo.'" width="100%"/>';
echo '</div>';
echo '<div style="clear:both"></div>';
echo '<a class="product-content">'.$row["pb_content"].'</a>';
echo '</div>';
echo '</div>';
$temp_result = $row["pb_title"]; // added this to save previous result
}
Make sure that programing should be effective for that you need to have following ideas:
1) Here you no need to use if($result) because when the sql results are true then only it will allow inside the condition
2) While programing try to avoid more if else condition for making efficient.
<?php
$select_brand = "SELECT * FROM tblProduct_Brand WHERE pb_display='display'";
$result = mysqli_query ($mydatabase, $select_brand);
while($row = mysqli_fetch_array($result))
{
$pb_feature_image = substr(($row['pb_feature_image']),3);
$pb_logo = substr(($row['pb_logo']),3);
$temp_result;
if($temp_result == $row["pb_title"]) { $style = 'style="padding:20px; background-color:red;"'; }
else { $style = ' style="padding:20px; background-color:grey;"'; }
echo '<div '.$style.' >';
echo '<div style="display:inline-block;width:340px;height:250px;vertical-align:top;">';
echo '<img src="'.$pb_feature_image.'" width="100%" height="100%"/>';
echo '</div>';
echo '<div style="display:inline-block;width:330px;height:250px;padding-left:10px;">';
echo '<div style="height:40px;width:80px;float:right">';

echo '</div>';
echo '<div style="clear:both"></div>';
echo '<a class="product-content">'.$row["pb_content"].'</a>';
echo '</div>';
echo '</div>';
$temp_result = $row["pb_title"];
