Any ideas? Hi there. I'm totally new (about a week!) with php and mysql and am encountering a problem that perhaps someone can help me with?
I've looked through to see if a similar problem has appeared or been solved, but without success, so apologies if I am repeating something.
In php I am trying to update 7 fields from a form from which a user has edited/modified any of the fields in a chosen record (except id).
Here is the code:
$id=$_GET['id']; Earlier I posted about how to best deal with a calculated field in MySQL and was advised not to store the value in the database. So, I took my calculated value out of the tables. I can select based on the calculated value
SELECT ... right_count, wrong_count, right_count + wrong_count AS Total_Count, right_count / (right_count + wrong_count) AS Right_Percent ...but now I want to UPDATE based on Right_Percent. The old code was: UPDATE leitner_vcard_boxes SET box=box+1 last_reboxed_date='$today' where box<7 AND last_reboxed_date<'$cutoff_date' and right_percent<='$score'The only way I can think of updating is something like: UPDATE leitner_vcard_boxes SET box=box+1 last_reboxed_date='$today' WHERE box<7 and last_reboxed_date<'$cutoff_date' AND Right_Percent IN (SELECT right_count, wrong_count, right_count / (right_count + wrong_count) AS Right_Percent FROM leitner_vcard_boxes WHERE Right_Percent,='$score');Will using a subquery even work? Is there a better way? To further complicate things, I loop through 5 score/cutoff date pairs (so that a lower score gets reboxed faster than a higher score). I imagine it would be more efficient to try to combine it all into a single query.
$cutoff_scores=array(25=>7,50=>14,75=>28,90=>40);
foreach ($cutoff_scores as $score => $rebox_interval){
$today=date('Y-m-d');
$interval=$rebox_interval.' days';
$cutoff_date=date_sub($today, date_interval_create_from_date_string($interval));
$query="UPDATE leitner_vcard_boxes SET box=box+1 last_reboxed_date='$today' where box<7 and last_reboxed_date<'$cutoff_date' and right_percent<='$score'";
$result= mysqli_query($link, $interval);
}
I need to update a particular table and there be a whole lot of field names. I'd like to do it without having to use them the same way you can access then like $row[12] after a "select" query. The standard for updating (at least how I write it) goes like this ... Code: [Select] $query = "UPDATE linguistics SET welcome1='$var3', welcome2='$var4' WHERE language = '$lengua'"; Well, I'd like to do it where I don't have to name welcome1 and welcome2, but instead refer to their numerical position within the database. On a "select" query we can do this. Can this be done on an update? Something perhaps like ... Code: [Select] $query = "UPDATE linguistics SET 3='$var3', 4='$var4' WHERE language = '$lengua'"; ... where 3 and 4 represent the 4th and 5th fields respectively. I know that this particular phrasing doesn't work because I've tried it, but surely there has to be something. This will save me LOTS of time. Thanks!! Hi, when I submit a form I want to update a field in the "daterange" table. In the form the id field (RID) from "daterange" is selected prior to submit. Basically, I want to change the STATUS field to B (from A). The structure of daterange table is as follows: RID (key field) DEND MONTH DATE SITE PRICE STATUS What is the easiest way to accomplish this? Here is the code from the form (if it will help)... Code: [Select] <?php //************************************** // Page load dropdown results // //************************************** function getTierOne() { $result = mysql_query("SELECT DISTINCT MONTH FROM daterange") or die(mysql_error()); while($tier = mysql_fetch_array( $result )) { echo '<option value="'.$tier['MONTH'].'">'.$tier['MONTH'].'</option>'; } } //************************************** // First selection results // //************************************** if($_GET['func'] == "drop_1" && isset($_GET['func'])) { drop_1($_GET['drop_var']); } function drop_1($drop_var) { include_once('db.php'); $result = mysql_query("SELECT * FROM daterange WHERE DEND > DATE(NOW()) AND STATUS='A' AND MONTH='$drop_var' ORDER BY DATE, SITE") or die(mysql_error()); echo '<select name="RID"> <option value=" " disabled="disabled" selected="selected">Choose a Reservation</option>'; while($drop_2 = mysql_fetch_array( $result )) { echo '<option value="'.$drop_2['RID'].'">'.$drop_2 ['DATE']. ', '.$drop_2 ['SITE'].

My situation is that I will have multiple devices writing to a database, and in one case the time that is being kept track of is important. And the devices writing to the database are a bit difficult to keep accurate times on, so instead of writing the time from the devices themselves, I was hoping I could just have a field update itself. I know it can be done on INSERT, but I do not want to do an INSERT every time.
Thanks!
Yesterday, I created a topic about how I could update records and I managed to achieve that successfully. Now I have another dilemma. When I have a specific record I want to update, I want to change a category ID of an product (e.g. change it from 1 to 2) but how do I go about doing this? Here is my code thus far: Code: [Select] <?php require_once ('./includes/config.inc.php'); require_once (MYSQL); $id=$_GET['prodID']; $results = mysqli_query($dbc, "SELECT * FROM product WHERE prodID=".$_GET['prodID'].""); $row = mysqli_fetch_assoc($results); ?> <form action="" method='POST'> Product ID: <input type="text" value="<?php echo $row['prodID'];?>" name="prodID" /> <br /> Product: <input type="text" value="<?php echo $row['product'] ;?>" name="product" /> <br /> Product Description: <input type="text" value="<?php echo $row['prod_descr'] ;?>" name="prod_descr" /> <br /> Category: <select name="category"> <option value="<?php echo $row['catID'];?>"></option> </select> Price: <input type="text" value="<?php echo $row['price'] ;?>" name="price" /> <br /> In Stock: <input type="text" value="<?php echo $row['stock'] ;?>" name="stock" /> <br /> <br /><input type="submit" value="save" name="save"> </form> <?php if(isset($_POST['save'])) { $id = $_POST['prodID']; $product = $_POST['product']; $descr = $_POST['prod_descr']; $price = $_POST['price']; $stock = $_POST['stock']; // Update data $update = mysqli_query($dbc, "UPDATE product SET product='$product', prod_descr='$descr', price='$price', stock='$stock' WHERE prodID=".$_GET['prodID'].""); header( 'Location: update_save.php' ) ; } ?> Or something like that... I am not sure how to put this.. Anyway, I'll just get started with explaining my problem. I have an admin-page in which you can delete the comments given on blogs, using checkboxes and clicking on a button with the value 'verwijderenSubmit'. The deletion part works just fine, nothing wrong. However, I also want to be able to EDIT the comments with an other button called 'bewerkenSubmit', using the same checkboxes that I use for deletion. Selecting the right CID (CommentID) is no problem, because that works the same as the deletion-part, but selecting the right textarea to update into the database is the problem... I uploaded a file here with the whole code: http://dhost.info/ddfs/myproblem.html I escaped the textarea within with square brackets, because otherwise the whole textarea would screw up.. I also added <!-- RELEVANT CODE --> to select the parts that I need to change. Well, I hope you understand my problem and can help. 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! Hello All,
Being a newbie at PHP coding I'm at my wits end trying to figure out:
a) how to pull-in values from a delimeted text field (in a MySQL table) and check/select the appropriate checkboxes, based on the values that were stored in the text field,
b) how to write any changes (made by the user) back to the tables' text field.
Note that this is for an "update.php" file/process.
My "create.php" file/process uses the following HTML to display and accept the checkbox values:
<div class="control-group"> <label class="control-label">Limited Time Sale Days:</label> <div class="lts-checkboxes-container"> <label class="indent-to-the-left"> <input class='lts-checkbox' type='checkbox' name='limited_time_sale[]' value ='F'><span class='no-highlight'>Fri</span> </label> <label><input class='lts-checkbox' type='checkbox' name='limited_time_sale[]' value ='Sa'><span class='no-highlight'>Sat</span></label> <label><input class='lts-checkbox' type='checkbox' name='limited_time_sale[]' value ='Su'><span class='no-highlight'>Sun</span></label> <label><input class='lts-checkbox' type='checkbox' name='limited_time_sale[]' value ='M'><span class='no-highlight'>Mon</span></label> <label><input class='lts-checkbox' type='checkbox' name='limited_time_sale[]' value ='Tu'><span class='no-highlight'>Tue</span></label> <label><input class='lts-checkbox' type='checkbox' name='limited_time_sale[]' value ='W'><span class='no-highlight'>Wed</span></label> <label><input class='lts-checkbox' type='checkbox' name='limited_time_sale[]' value ='Th'><span class='no-highlight'>Thu</span></label> </div> </div>And the code (certainly not the best code in the world, but it works) to collect, delemit/concatenate, and save to DB is as follows:
if(empty($_POST['limited_time_sale']))
{
// echo("You didn't select any weekday.");
$selected_lts = '';
$limited_time_sale = '';
}
else
{
$limited_time_sale = $_POST['limited_time_sale'];
$N = count($limited_time_sale);
$selected_lts = '';
// echo("You selected $N DoW(s): ");
for($i=0; $i < $N; $i++)
{
// echo($limited_time_sale[$i] . " ");
if ($i < ($N - 1))
{
$selected_lts .= $limited_time_sale[$i] . "-";
}
else
{
$selected_lts .= $limited_time_sale[$i];
}
}
}
if(!empty($selected_lts)) { $limited_time_sale = $selected_lts; }
Now, I've figured out how to bring-in, and separate the stored values using the following code, however I have no idea what to do next...in order to have only the approprite boxes checked/selected (in the event that all boxes were not selected during the create stage).
$limited_time_sale = isset($values['limited_time_sale']) ? $values['limited_time_sale'] : '';
$checked_lts = explode("-", $limited_time_sale);
In my "update.php" file, the HTML for the forms' checkboxes is as follows:
<div class="control-group"> <label class="control-label">Limited Time Sale Days:</label> <div class="lts-checkboxes-container"> <label class="indent-to-the-left"> <input class='lts-checkbox' type='checkbox' name='limited_time_sale[]' value ='F' <?php echo $lts1; ?>><span class='no-highlight'>Fri</span> </label> <label><input class='lts-checkbox' type='checkbox' name='limited_time_sale[]' value ='Sa' <?php echo $lts2; ?>><span class='no-highlight'>Sat</span></label> <label><input class='lts-checkbox' type='checkbox' name='limited_time_sale[]' value ='Su' <?php echo $lts3; ?>><span class='no-highlight'>Sun</span></label> <label><input class='lts-checkbox' type='checkbox' name='limited_time_sale[]' value ='M' <?php echo $lts4; ?>><span class='no-highlight'>Mon</span></label> <label><input class='lts-checkbox' type='checkbox' name='limited_time_sale[]' value ='Tu' <?php echo $lts5; ?>><span class='no-highlight'>Tue</span></label> <label><input class='lts-checkbox' type='checkbox' name='limited_time_sale[]' value ='W' <?php echo $lts6; ?>><span class='no-highlight'>Wed</span></label> <label><input class='lts-checkbox' type='checkbox' name='limited_time_sale[]' value ='Th' <?php echo $lts7; ?>><span class='no-highlight'>Thu</span></label> </div> </div>Attached picture shows that selected checkboxes are saved to the text field as/in the format of "F-Sa-Su-M-Tu-W-Th" - if all checkboxes/weekdays were selected....or as "Sa-M-W-Th" - if only Sat, Mon, Wed, and Thu checkboxes were selected Thanks.
