I am having a few issues concatenating a string and then outputting the value.
In the database I have a column titled 'featured_price'. In that column is specified another column that will hold the value I am trying to acquire, however, I need to append '_term' to the end and then get the column from the database.
So I need to have two outputs:
1) featured_price
2) specified_column_term
This is my PHP:
$rows = $wpdb->get_results("SELECT * FROM specified_details WHERE id='$id'");
foreach ($rows as $result) {
echo $result->featured_price;
$featuredprice = $result->featured_price;
$featuredterm = $featuredprice. "_term";
echo $result->$featuredterm;
}
When I var_dump() I just get this array(0).
You may have a mistake there on line
echo $result->$featuredterm;
Shouldnt it be
echo $rows->$featuredterm;
?

Please see below code
$template->customer = $rephome->getCustomer($user_id);
foreach($template->customer as $value){
echo $value->customer_id;
}
The first line of code will get result of a query. it was fetched as object.
the second line of code will echo out all of the customer id field from the query result. This works fine. it will echo out 1234567.... to however many id there is.
however if I change the code to like the one below, the echo will only get the first customer_id. ie. 1
$template->customer = $rephome->getCustomer($user_id);
foreach($template->customer as $value){
$something = $value->customer_id;
}
echo $something;
so the question is what is the correct way of assigning the list of results to $something. so I can use $something as a list of ids to be used to run other querys.
in another word. I am trying to use result of first query to run a second query.
$template->customers = $rephome->getCustomer($user_id);
foreach ($template->customers as $value){
$template->orders = $rephome->getOrder($value->customer_id);
}
the above code give me the same result as echo. I will get all the customer id as intented but I will only get repeating order information that is assoicated with first customer id. instead of different orders associated to different customer id.
Yes of course, cause you are overwriting the $something variable each iteration of the foreach loop and echo the result afterwards.
A way to solve this is by using an array:
$something = array();
foreach($template->customer as $value){
$something[] = $value->customer_id;
}
This way you are adding a value to the array each iteration.
so the question is what is the correct way of assigning the list of
results to $something. so I can use $something as a list of ids to be
used to run other querys.
To use the ID's for another SELECT query, so it will only return records associated with the id's inside the array, you can do this for example:
$sql = 'SELECT * FROM `table`
WHERE `id` IN (' . implode(',', array_map('intval', $something)) . ')';
Which will result in something like:
$sql = 'SELECT * FROM `table` WHERE `id` IN (1,2,4,6,7,10)';
Does this answer your question?
On this code:
foreach($template->customer as $value){
$something = $value->customer_id;
}
$something will be overrriten on each loop for a new value. So, on last line, your code will output the last value of resultset´s $value->customer_id.
Got it ??
So, use an array:
$something = array();
foreach($template->customer as $value){
$something[] = $value->customer_id;
}
Try this within your loop:
$something[] = $value->customer_id;
and then outside your loop:
print_r($something);
I have a simple query which will fetch all from a users tables
$query = $this->pdo->prepare('SELECT * FROM `users`');
$query->execute();
return $query->fetchAll();
Then i would have a foreach loop like
$results = $User->getUser();
foreach($results as $result){
echo $result['fname'];
echo $result['lname'];
}
But is there a way to display each of the fields without writing each field name?
First, fix your return fetchAll to specify the return style like so:
return $query->fetchAll(PDO::FETCH_ASSOC);
Then you can use an inner loop with your outter loop like so:
//get the results
$results = $User->getUser();
//loop over the results, setting $result to an array representing each row
foreach($results as $result){
//loop over each $result (row), setting $key to the column name and $value to the value in the column.
foreach($result as $key=>$value){
//echo the key and value.
echo "{$key} = {$value}<br>";
}
}
This will output all columns and their value regardless of what columns there are in the array. Following the comments, you can see what I do is, using your code, loop over the outer array that is an array of each row from the query. Then loop over the array from each row getting the column name and the value in that column. For now I am just echo'ing out the column and value. You would likely want to do more like echo this out to a table or whatever your end goal is.
I've created this thing to get a TEXT value from my database.
$query1 = "SELECT * FROM `ma_apps` WHERE `assignedto`='$_SESSION[username]'";
$result1 = mysql_query($query1) or die(mysql_error());
$Appdata = mysql_fetch_array($result1) or die(mysql_error());
and then:
$app_content = $Appdata['1'];
echo $app_content;
but it echos and says nothing, although it's the right name of the key. And I already checked if I can get another value from the database from a key that is considered as "TINYINT", and it works well. But I fail to echo/get the "TEXT" keys from my database.
Thanks.
i think you want to access to the second value in the array.
try this
$Appdata[1];
otherwise use mysql_fetch_assoc to create a array with the field name as key
If your string resembles an HTML tag then it's going to be treated like an HTML tag and not show as a string on the screen. It's worth checking view source on your browser to see if your string starts with a <.
$query1 = "SELECT * FROM `ma_apps` WHERE `assignedto`='{$_SESSION['username']}'";
Also,
$Appdata[1];
try echo $Appdata[0]; because you are asking for a column with name '1', vs asking for the index 1
You should do
$query1 = "SELECT * FROM `ma_apps` WHERE `assignedto`='".$_SESSION[username]."'";
and
$app_content = $Appdata[0];
var_dump($Appdata) check the values inside the variable and use it properly. Index is without '.
you can also just echo everything from the result set with:
<?php
mysql_data_seek($result1,0);
while ($row = mysql_fetch_array($result1)){
foreach ($row as $key => $value){
echo $key." - ".$value;
}
}
?>
Then you will see the key value pairs
I have searched for similar questions but cannot find the right answer to my specific one. I have a column (data) in my table (table) which contains comma separated values which are id's e.g.
Row 1= 4,5,45
Row 2= 5,8,9
Row 3= 5
I use an in_array function to retrieve the number of occurances for the $data value within the while loop. So I use an sql function to retrieve the number of times a certain value such as '5' occurs in all rows within the while loop.
The issue is that I can only retrieve the $data value if it is by itself (i.e. no commas just the integer by itself) so based on my example in the list, I can only retrieve 5 once (row 3). I would like to retrieve the value '5' three times as it appears in all the rows. Here is my code below and any help would be appreciated. The $selectiontext variable is what the user enters from the form.
$sql_frnd_arry_mem1 = mysql_query("SELECT data, id FROM table WHERE data='$selectiontext'");
while($row=mysql_fetch_array($sql_frnd_arry_mem1)) {
$datacheck = $row["data"];
$id = $row["id"];
}
$frndArryMem1 = explode(",", $frnd_arry_mem1);
if (($frnd_arry_mem1 !=="") && (!in_array($id, $frndArryMem1))) {echo $id;}
Thank you.
you keep overwriting the variables $datacheck and $id, leaving you with only the last version of them. move that curly brace down two lines, like this:
$sql_frnd_arry_mem1 = mysql_query("SELECT data, id FROM table WHERE data='$selectiontext'");
while($row=mysql_fetch_array($sql_frnd_arry_mem1)) {
$datacheck = $row["data"];
$id = $row["id"];
$frndArryMem1 = explode(",", $frnd_arry_mem1);
if (($frnd_arry_mem1 !=="") && (!in_array($id, $frndArryMem1))) {echo $id;}
}
I am not totally sure of your requirements, is not very clear what you intend to do as part of the code is missing.
I assume you want to check each row of a comma separated of a CSV file ($frnd_arry_mem1 being the row) against your data in column data, if any of those comma separated data (not) occurs.
Assuming you are already looping through your CSV, this would be the code (non tested):
NOTE: might be inefficient retrieving data within a loop, if you can do otherwise - but I cant tell as I dont kow the full specs of your script.
If I got the specs wrong please clarify, I will try to help further.
$sql = "SELECT data, id
FROM table
WHERE data='$selectiontext'";
$sql_frnd_arry_mem1 = mysql_query($sql);
$results = array();
// get values to check
while ($row = mysql_fetch_array($sql_frnd_arry_mem1))
{
$results[] = array(
'datacheck' => $row["data"],
'id' => $row["id"],
);
}
foreach ($results as $result)
{
$frndArryMem1 = explode(",", $frnd_arry_mem1);
$data = explode(',', $result['datacheck']);
foreach ($data as $d)
{
if (($frnd_arry_mem1 !=="") && (!in_array($d, $frndArryMem1)))
{
echo 'DEBUG: Record #' . $id . ' not found, value:' . $d . '</br>';
}
}
}
Hey all i have a mind bug with this wile loop , i am a bit of a noob
$sql_advanced_bio = mysql_query("SELECT * FROM bio_details WHERE mem_id='$id'");
while($row = mysql_fetch_assoc($sql_advanced_bio)){
$bio_time_family = $row["bio_time_family"];
}
So this is the php now in my HTML i have this
*php echo $bio_time_family *
Why dose it echo only one value ?
SIMPLE ANSWER
so i tried somethingh easier like this $bio_fun_family .= $row["bio_fun_family"].",";
and then this
$bio_fun_family = substr($bio_fun_family,0,-1);
I added the .next to the =
It appends the values
You need to store the values in an array, otherwise you're just overwriting one variable each time, so you'll just end up with the last value.
You also need to use a loop to echo out each value in the array.
$sql_advanced_bio = mysql_query("SELECT * FROM bio_details WHERE mem_id='$id'");
$bio_time_family = array();
while($row = mysql_fetch_assoc($sql_advanced_bio)) {
$bio_time_family[] = $row["bio_time_family"];
}
And then for the output;
foreach($bio_time_family as $b) {
echo($b . '<br />');
}
With each iteration of the while loop, you're assigning to $bio_time_family the newly extracted value. If you'd like to make an array of the, instead, use $bio_time_family[] = $row["bio_time_family"];
Because every time you run through the loop you're re-assigning $bio_time_family to the next row's value. Try calling echo directly in your loop or add the row to an array, then loop through that and output the rows
