PHP - Concatenation Inside Array Element Names
I'm wondering if this is at all possible:-
Code: [Select] $i = 7; $row_item['comment$i_name'] = "john"; with the $i in $row_item['item$i_id'] being replaced with whatever $i is set as sort of like this:- $row_item['comment.'$i'._name'] Is this sort of concatenation possible inside array element names as I can't seem to get it to work? Similar TutorialsMy Php Buddies, I have mysql tbl columns these:
id: Now, I want to display their row data by excluded a few columns. Want to exclude these columns: date_&_time account_activation_code account_activation_status id_verification_video_file_url password
So, the User's (eg. your's) homepage inside his account should display labels like these where labels match the column names but the underscores are removed and each words' first chars CAPITALISED:
Id: 1
For your convenience only PART 1 works. Need help on Part 2 My attempted code:
PART 1
<?php
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
// Query to get columns from table
$query = $conn->query("SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = 'members' AND TABLE_NAME = 'users'");
while($row = $query->fetch_assoc()){
$result[] = $row;
}
// Array of all column names
$columnArr = array_column($result, 'COLUMN_NAME');
foreach ($columnArr as $value) {
echo "<b>$value</b>: ";?><br><?php
}
?>
PART 2
<?php
//Display User Account Details
echo "<h3>User: <a href=\"user.php?user=$user\">$user</a> Details</h3>";?><br>
<?php
$excluded_columns = array("date_&_time","account_activation_code","account_activation_status","id_verification_video_file_url","password");
foreach ($excluded_columns as $value2)
{
echo "Excluded Column: <b>$value2</b><br>";
}
foreach ($columnArr as $value)
{
if($value != "$value2")
{
$label = str_replace("_"," ","$value");
$label = ucwords("$label");
//echo "<b>$label</b>: "; echo "$_SESSION[$value]";?><br><?php
echo "<b>$label</b>: "; echo "${$value}";?><br><?php
}
}
?>
PROBLEM: Columns from the excluded list still get displayed. Edited November 19, 2018 by phpsaneHi - good evening! thanks for the answer and all the help so far Oncemore the "Fetching-part" for a little parser-script: Here we go - new target urls: see the overview: http://dms-schule.bildung.hessen.de/index.html http://dms-schule.bildung.hessen.de/suchen/suche_schul_db.html Search by pressing the button "type" and then choose all schools with the mouse! Results 2400 schools: Here i can provide some "more help for getting the target!" - btw: see some details for this target-server: http://dms-schule.bildung.hessen.de/suchen/suche_schul_db.html?show_school=9009 http://dms-schule.bildung.hessen.de/suchen/suche_schul_db.html?show_school=9742 http://dms-schule.bildung.hessen.de/suchen/suche_schul_db.html?show_school=9871 well - you see i have to iterate over the sites - with a function /(a loop) http://dms-schule.bildung.hessen.de/suchen/suche_schul_db.html?show_school=1000 to 10000 BTW - after fetching the page i have to see which one are empty - those ones do not need to be parsed! Well - i want to do this with curl-multi since this is the most advanced way to do this: I see i have an array that can be filled I have to try it out...!! Well, I'm not pretty sure - but judging by the low level of PHP i have: I think that i may need a double array to define the URLs like: Can i do like so?: $urls = array( "siteone" => "suche_schul_db.html?show_school=%i", "sitetwo" => "suche_schul_db.html?show_school=%i", "sitethree" =>"suche_schul_db.html?show_school=%i" ); $params = array ( for ($i = 1; $i <= 10000; $i++) { // body of loop } // well i have to define the variables in a open form like abvove nand not below: // better than doing it like so: "siteone" => array(9009, 9742, 9871), ); then pass them to curl-multi as: foreach ($urls as $id => $url) { foreach ($params[$id] as => $param) { $i = $id . $param; $finalurl = sprintf($url, $param); $conn[$i] = curl_init($finalurl); I don't know if that's fits the needs tip that i am looking for but I hope so ;-) Can i do like so [see above]? What do yu think. i send you many greetings martin Hi guys; I've managed to find my way into something of a maze. <td> <a href="'Details/21/index.php'"?id= . $id .'>" . $row['id'] . "</a> </td> I'm looking at this line in the code. I realise it's currently in the wrong syntax but I'm just trying multiple different variations. At the moment I'm actually just trying to make it go to a static link but my real goal is to - get it to pick up the id number, of the id row I click, and concatenate that with the rest of my address string. Then use that as the href. Something like this: - "'Details/' + $id + '/index.php'" It's really confusing me though inside this loop and for some reason the id number is being picked up as an int, by the looks of things. It's getting above my level of understanding. Any chance one of you masters would through a n00b a lifeline?

Hey, sorry that I am posting this darn image upload script again, I have this almost finished and I am not looking to ask more questions when it comes to this script specifically.
With the script above I have that part where the script should store the ID numbers (the auto_increment column of the table) of the image files inside of one array and then the "implode()" function would get used on the array and then the ID numbers would get inserted into the "image_file_id" column of the "thread" table.
As you can see at the above part the script prints the following:
Array ( [0] => 542 )
Array ( [0] => 543 )
Array ( [0] => 544 )
And I am looking to insert into the column of the table the following:
542, 543, 544I thought of re-writing the whole image upload script since this happens inside the for loop, though I thought maybe I could be having this done with the script as it is right now. Any suggestions on how to do this? I want to fetch items from a database and be able to update their quantity by selecting a number from a drop down selection and press the button "Update quantity" to perform the action.
I have the following php code:
echo '<table border="4">
<tr>
<th>ID</th>
<th>Item Name</th>
<th>Current Quantity</th>
<th>New Quantity</th>
<th>Update</th>
</tr>';
for($i=0 ;$i<$k; $i++)
$z = $i+1;
//fetch data from database
$id = the id of the row that the entry/item is at
$item_name = the name of the item
$current_quantity = the current quantity of the item
//create a table of entries
echo '<tr'>
<td>'.$z.'</td>
<td>'.$item_name.'</td>
<td>'.$current_quantity.'</td>
<td>
<select id="quantity" name="quantity">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
.
.
.
</select>
</td>';
echo '<td>
<button type="button" value="'.$id.'" name="updatebtn" id="updatebtn">Update Quantity</button>
</td>';
echo '</tr>';
Where k = number or matches in database
The result is something like this:
///////////////////////////////////////////////////////////////////////////////ID // Item Name // Current Quantity // New Quantity // Update /// //////////////////////////////////////////////////////////////////////////// // 1 // Shoes // 10 // 12 // Update Quantity // //////////////////////////////////////////////////////////////////////////// // 2 // T-shirts // 5 // 8 // Update Quantity // //////////////////////////////////////////////////////////////////////////// // 3 // Watches // 4 // 2 // Update Quantity // //////////////////////////////////////////////////////////////////////////// The first 3 columns are populated by the database and New Quantity by the user. As soon as the user is done with the new quantity he/she presses "Update Quantity" to update the database. Below is the jQuery code i use:
$(document).ready(function(){
$('#updatebtn').click(function(){
//i use this value to find the exact entry in the database
var id = $('#updatebtn').attr('value');
var quantity_selected = $('select#quantity option:selected').attr('value');
$.ajax({
type: "POST",
url: "js/ajax/updatequantity.php",
data: {id: id, new_quantity: quantity_selected}
});
//this is for testing
alert('ok');
});
});
The updatequantity.php script just takes the new quantity and the row of the entry and updates the value.
My problem is:
If i press the "Update Quantity" of the item "Shoes", i see the pop-up "ok" and the quantity is updated. But when i try to do the same for the 2 other items (T-shirts and watches), i get nothing.
Does my js script has trouble to differentiate between the "Update Quantity" buttons? Is there another approach?
ps: i am doing this using wamp on my localhost
Thanks in advance.
Hi all, I have the following MySQL insert query: Code: [Select] $insert= mysql_query ("INSERT INTO tablename (column1,`".$EXPfields."`) VALUES ('$something','".$EXPvalues."')"); where $EXPfields is an array of table-field-names and $EXPvalues is an array of table-field-values. Now I want to write an equivalent query, but using UPDATE instead of INSERT INTO, but I don't want to write out all the field names/values separately, but again want to use $EXPfields and $EXPvalues. So something like this: Code: [Select] $update = mysql_query ("UPDATE tablename SET (column1,`".$EXPfields."`) = ('$something','".$EXPvalues."') WHERE .... "); Is this possible? If so, what is the proper syntax? Thanks! Hi, I want to store files to variable array using glob() like $files[0] = xyz.txt $files[1] = pqr.txt . . . $files[n] = nfile.txt I know how to list files from directory using glob() Code: [Select] <?php foreach (glob("*.txt") as $filename) { echo "$filename size " . filesize($filename) . "\n"; } ?> How can I do that ? I'm creating a quick survey app for my son's cub scout pack's end-of-year surveys. There are two sets of questions: those where they want the responses to be completely anonymous and those questions where we need to know who filled out the response (people volunteering for positions, etc) I'm storing the responses in the db as two separate arrays, $anon and $nonAnon $anon[0] will be an array containing all the questions: $anon[0][0] = Survey question # 1 $anon[0][1] = Survey question #2, etc. The responses will be stored as arrays and placed in $anon as the 2nd element: $anon[1][0][0] = first response, answer to the first question $anon[1][0][1] = first resopnse, answer to the 2nd question $anon[1][1][0] = 2nd response, answer to the 1st question Etc. The pack leadership is concerned that no one would be able to reconstruct which anon response belonged to whom by matching up the order of the anon answers with the non-anon answers. Therefore I'd like to shuffle at least the anon responses. The long answer would be to build a temp array using the elements in $anon[1] and then shuffle that array and then reassign it to $anon[1]. Is there a way to use shuffle directly on $anon[1] without having to build a temporary array, shuffling it, then replacing the elements of $anon[1]? How would you access the number 10 in the $arr array? Hi Everyone I am looking to just grab the first element of an array and do something to it but i only want this extra bit off code on the first value off the array. Here is my array echo "<pre>"; print_r($_SESSION); echo "</pre>"; Array ( [attach] => Array ( ) [backups-2] => true [dnb] => true [house] => true [tech-house] => true [uk-garage] => true [uk-grime] => true [uk-hip-hop] => true [uncategorized] => true [warehouse] => true [value] => Array ( [0] => Array ( [tune_name] => Music/dnb/Abort_Delta Heavy_192.mp3 [tune] => http://isdmusic.s3.amazonaws.com/Music/dnb/Abort_Delta Heavy_192.mp3 [submit] => Listen ) [1] => Array ( [tune_name] => Music/dnb/Acid Bath (Northern Lights remix)_Twisted Individual_192.mp3 [tune] => http://isdmusic.s3.amazonaws.com/Music/dnb/Acid Bath (Northern Lights remix)_Twisted Individual_192.mp3 [submit] => Listen ) [2] => Array ( [tune_name] => Music/dnb/Awkward_Inside Info_192.mp3 [tune] => http://isdmusic.s3.amazonaws.com/Music/dnb/Awkward_Inside Info_192.mp3 [submit] => Listen ) [3] => Array ( [tune_name] => Music/dnb/Awkward_Inside Info_192.mp3 [tune] => http://isdmusic.s3.amazonaws.com/Music/dnb/Awkward_Inside Info_192.mp3 [submit] => Listen ) ) ) so i just what to effect the first value what to and autostart to it???

And then from a table I get the variable $cat_cd. $cat_cd contains 'F' so it refers to 'Personal: Sport' If I want to put that in $category, how would I write that? I thought it might be .... $category = $cats['$cat_cd']; I tried that and it didn't work .
Thanks
Hi there! Ok I've a very simple code he $character = array (name=>"Joe", occupation=>"Programmer", age=>30, "Learned language "=>"Java" ); print_r($character); echo "<br/>"; foreach ( $character as $key=>$val ){ print "$key = $val <br>"; } The output is: Code: [Select] Array ( [name] => Joe [occupation] => Programmer [age] => 30 [Learned language ] => Java ) name = Joe occupation = Programmer age = 30 Learned language = Java Now instead of returning all the other elements, I just need to display only the first element in the array that is the value 'Joe'. I tried $val[name]; Output I get is not what I want: Code: [Select] J P J All responses/feedbacks is always welcomed Thank you! Given the following example code; if a function were passed the value of $id is there a way to point to the previous or next element in the array to retrieve their values. thanks Code: [Select] $arr = array(); for( $i = 0; $i < 10; $i++ ) { $id = mt_rand() + $i; $arr[$id] = "some value"; } function getValue( $id ) { $element = $arr[$id]; //point to previous element or next element beginning from $element position } Hello All, I have used a function to collect a users information from the database.

Hi, I have an array key whose value is a line of html in quotes, the problem is , I don't know how to do it. Lol. Any help greatly appreciated because the below code is generating an error in my editor. Thank you. Derek here is the line. Code: [Select] 'level_1'=>"<img src='<img src='sundragon_environments/ocean/ocean1_FRAME.jpg'/>'", EDIT: actually I managed to fix the error adding a semicolon after the parenthesis. Is this array correct please? Code: [Select] $currentLocation = array ( 'teardrop_ocean_bg' => array ( 'level_1'=>"<img src='<img src='sundragon_environments/ocean/ocean1_FRAME.jpg'/>'" ) ); it's not finished yet. I am using session variables to keep track of what is in a shopping cart. I can add the items to the cart quite easily enough. But my problem is that I can't delete a specific item in the cart. Below is a summary of what the array looks like $Item1=array("ProdID"=>"Hat","Color"=>"Not Needed","Size"=>5); $Item4=array("ProdID"=>"Shirt","Color"=>"Green","Size"=>"L"); $Item2=array("ProdID"=>"Pants","Color"=>"Not Needed","Size"=>"32x32"); $Item3=array("ProdID"=>"Socks","Color"=>"Not Needed","Size"=>"Not Needed"); $NumItems=4; $TestArray=array("NumItems"=>$NumItems,1=>$Item1,2=>$Item2,3=>$Item3,4=>$Item4); However when I attempt to delete any of the top level elements (1,2,3,4,NumItems), I either end up deleting only the last element (4) or somehow taking out 2 of them. I know that this must be an easy fix but I've looked at it for so long that I can't seem to figure out what the problem is. below is the code that I use to delete the Item from the array Code: [Select] $ItemNum=$_GET['item']; if ($ItemNum=="All"){ $ItemNum=$_GET['item']; if ($ItemNum=="All"){ unset($TestArray); unset($TestArray['NumItems']); unset($_SESSION['OrderTotal']); //header("Location:Cart.php?act=view"); } else{ $TestArray['NumItems']=$TestArray['NumItems']-1; if($TestArray['NumItems']<1) { unset($_SESSION['OrderTotal']); unset($TestArray); unset($TestArray['NumItems']); } else { unset($TestArray[$ItemNum]); } Can anyone take a look at this and point me in the correct direction? What I am after is to delete any element of the top array and keep the rest. I am trying to break down an array to make it easier to read. An array that looks like Array (
=> 0 [1] => 0 [2] => 0 [3] => 0012844 1 [4] => 37 [5] => 1 etc...) I want to display it like:
Code: [Select] [0] => 0 [1] => 0 [2] => 0 etc... how can this be accomplished. Is there any limit to the length of an array element in a flat data file? For instance, I have a flat file that I might end up having 200 rows, with each row containing 15 elements. Most of the elements will be about 20 characters or less, but a couple of the elements might be 300-400 characters. I'm guessing there is no limit. And since each row will be longer than one "line" in a .txt file, how best to mark the end of a row? [I assume that using a database is probably the better way to do this, but on this particular website I'm working on that isn't an option.] Hi all, Is there a function or method to delete element from current position in array without knowing the index. For example: $ar = array( 1, 2, 3, "test", 4, 5, "test2" ); while( $v = current( $ar ) ) { if( key( $ar ) == "test" ) { // remove element from the array where key equals "test" // i could count every cycle and splice from that index but i wonder can that be done without it // i am looking at the php array functions but i can't find any that will delete from element from current position in array echo 'key( $ar ) je test. key( $ar ): ' . key( $ar ); } next( $ar ); } One thing that i don't understand is that when i run example above the "test" key is found and when i echo it it gives me 0. |
