I'm new to web development and I'm trying to create editable database interface. I have got checkboxes in every row and an edit button. I need to update table(in database) when button clicked(rows that are checked). However I can't get current values in cells. I tried contentedittable div to display attiributes.
<?php while ( $rows = mysql_fetch_array($result)): ?>
<td align="center" bgcolor="#FFFFFF"><input name="need_delete[<?php echo $rows['UniqueID']; ?>]" type="checkbox" id="checkbox[<?php echo $rows['UniqueID']; ?>]" value="<?php echo $rows['UniqueID']; ?>"></td>
<td bgcolor="#FFFFFF"><div contenteditable><?php echo $rows['Timestamp']; ?></div></td>
<td bgcolor="#FFFFFF"><div contenteditable><?php echo $rows['Name']; ?></div></td>
<td bgcolor="#FFFFFF"><div contenteditable><?php echo $rows['Email']; ?></div></td>
<?php endwhile; ?>
I also tried to give unique names to divs, but it didn't work. I want to get current values from there if possible.
<?php
if( ! empty($_POST['edit']) ){
$query = 'UPDATE `asd` SET `Timestamp` = '????' WHERE `UniqueID`='.(int)$id;
mysql_query($query);
}
?>
Checkboxes work fine when I delete rows from table. Any suggestions ?
Thanks.
There are several javascript libraries that help with this problem:
x-editable http://vitalets.github.io/x-editable/ (bootstrap)
datatables https://datatables.net/ (jquery)
I had a similar issue that I solved here:
http://www.abrandao.com/2019/12/saving-contenteditable-html-using-php/
basically, it involves reading the HTML and using PHP parser to exctract the tag and the update the data

I'm currently working on a table that contains 'Name', 'Info', 'Price' and 'Duration'. However the PHP-Script is connected to a database.
I want to autofill the tablecells: 'Name', 'Price', 'Duration' via the Database by using PHP and SQL and that works perfectly fine for me. Though, I want to customize the content that's in the individual Info cells (e.g. Readmore jQuery and redirect to other pages).
I tried a little bit with using tags inside the Database and other weird stuff which, obviously, didn't work.
Is there a more elegant way of solving my problem than setting up a complete normal table without PHP/SQL, where I'd have to put in every bit of data about Name,Price and Duration manually?
<table class="table table-bordered table-hover tablesorter row sortable">
<thead>
<tr>
<th class="header">Name</th>
<th class="hidden-xs">Info</th>
<th>Price (in Euro)</th>
<th>Duration</th>
</tr>
</thead>
<tbody>
<?php
//Connect to Database
$db=mysql_connect ("xxxx", "xxxx", "xxxx") or die ('Oops! Da hat wohl' . mysqli_error(). 'Mist gebaut');
//Choose Database
$mydb=mysql_select_db("massageke_de");
//Query Database
$sql="SELECT * FROM Angebote";
//-run the query against the mysql query function
$result=mysql_query($sql);
//Show Results
while($row=mysql_fetch_array($result)){
//Start table ?>
<tr>
<td class="col-sm-2"><?php echo $Name =$row['Name'] ; ?></td>
<!--In this <td>-tag I want to put long textes with links-->
<td class="hidden-xs col-sm-5">echo $Name =$row['Info'];?<</td>
<td class="col-sm-2"><?php echo $Preis =$row['Preis']; ?></td>
<td ckass="col-sm-1"><?php echo $Dauer =$row['Dauer']; ?></td>
</tr>
<?php } ?>
</tbody>
</table>
Thanks in advance for helping.
Don't bother asking me additional questions.
P.S.: I hope you can help, without needing the CSS of Bootstrap, that I used.
P.P.S.:I know that my PHP-Script is not protected against PHP-Injection
(but I want to and will learn how to secure it)
Edit: As Jester asked for it. I made it quickly with photoshop because I think an image can express much better, what I want to achieve, than my poorly coding-skills.
Get to the image
Seems to me like the easiest way would be to just edit the info column in the database for each? If you want to do it in php i'd suggest making an array using the names (ids would be better but it seems you don't have access to those?) as keys:
$info['Aroma Teilkoerper'] = "Text about aroma teilkoerper";
$info['Aroma Ganzkoerper'] = "Text about aroma ganzkoerper";
and so on until you have all. Then in the loop:
//Show Results
while($row=mysql_fetch_array($result)){
//Start table ?>
<tr>
<td class="col-sm-2"><?php echo $Name =$row['Name'] ; ?></td>
<!--In this <td>-tag I want to put long textes with links-->
<td class="hidden-xs col-sm-5">echo $Name =$info[$row['Name']];?></td>
<td class="col-sm-2"><?php echo $Preis =$row['Preis']; ?></td>
<td ckass="col-sm-1"><?php echo $Dauer =$row['Dauer']; ?></td>
</tr>
<?php } ?>
Hoping that is a workable solution for you? (also you had a syntax error in your closing php tag.
echo $Name =$row['Info'];?< // <----- should be ?> of course
supposing you have a table generated via php from a mysql database,
eg,
<?php do { ?>
<tr>
<td><?php echo $row_sampleOA_set['concentration']; ?> </td>
</tr>
<?php } while ($row_sampleOA_set = mysql_fetch_assoc($sampleOA_set)); ?>
how would you go about using the contenteditable attribute to make the table cell editable and the edit to update the database?
I will have to mention first that I have searched for a Google and stackoverflow and anywhere else, as well as tried to use scripts given in forums and write my own ones, but nothing worked for me. I am completely stuck.
So, all I try to do is to write a script that will delete checked rows from MySQL table. Here is my HTML written inside of a PHP file:
<tr class="noP">
<td class="check"><input class="checkbox" name="checkbox[]" type="checkbox" value="'.$row["PID"].'"/></td>
<td class="id">'.$row['PID'].'</th>
<td>'.$row["name"].'</th>
<td>'.$row["surname"].'</th>
<td>'.$row["pcode"].'</th>
<td class="address">'.$row["address"].'</th>
<td class="email">'.$row["email"].'</th>
<td>'.$row["phone"].'</th>
<td class="education">'.$row["education"].'</th>
<td class="remarks">'.$row["remarks"].'</th>
</tr>
for here $row = mysql_fetch_assoc($qParts);, so this array is just a collector of field values from MySQL DB.
Basically, all I try to do is just a table with all the participants listed with ability to delete selected ones.
I would highly appreciate any help provided. Thank you!
This should help you:
foreach($_REQUEST['checkbox'] as $val)
$delIds = intval($val);
$delSql = implode($delIds, ",");
mysql_query("DELETE FROM table WHERE PID IN ($delSql)");
So, that takes your input array from $_GET/$_POST, sanitises it (a little), then implodes it to get a list of IDs (e.g. 5, 7, 9, 13). It then feeds that into an SQL statement, matching on those IDs using the IN operator.
Note that you should do this using prepared statements or similar. It's been a while though, so I can't write them off-hand, but this should give you the gist of it.
To do this using PDO, have a look here. It's a bit more complex, since you need to dynamically create the placeholders, but it should then work the same.

I think I can help you out. I had the same issue during my semester project. The problem can be solved using HTML and PHP alone.
I am assuming that PID is the primary key in your table. The trick here is to put the entire table in a form so that it looks like this:
<form action="/*NAME OF THIS PAGE HERE*/.php" method="POST">
<?php
if(isset($_POST['delete'])) //THE NAME OF THE BUTTON IS delete.
{
foreach ($_POST["checkbox"] as $id){
$de1 = "DELETE FROM //table-name WHERE PID='$id'";
if(mysqli_query($conn, $de1))
echo "<b>Deletion Successful. </b>";
else
echo "ERROR: Could not execute";
}
}
if(isset($_POST['delete'])){
echo"<b>Please make a selection to complete this operation.</b>";
}
?>
</br>
<!-- below you will see that I had placed an image as the delete button and stated its styles -->
<button type="submit" name="delete" value="delete" style="float:right;border:none; background:none;">
<img style="width:55px; height:55px;margin-left:10px; margin-bottom:6px; float:left;" src="images/del.png">
</button>
<table>
<thead>
<tr>
<th>#</th>
<th>PID</th>
<th>NAME</th>
<th>SURNAME</th>
<!--REST OF THE TABLE HEADINGS HERE -->
</tr>
<?php $fqn="SELECT * FROM //table-name here;
$fqn_run=mysqli_query($conn,$fqn);
while($row=mysqli_fetch_array($fqn_run)):?>
</thead>
<tbody>
<tr class="noP">
<td class="check"><input class="checkbox" name="checkbox[]" type="checkbox" value="<?php echo $row["PID"];?>"></td>
<td><?php echo $row['PID'];?></td>
<td><?php echo $row["name"];?></td>
<td><?php echo $row["surname"];?></td>
<!-- REST OF THE ROWS HERE -->
</tr><?php endwhile;?>
</tbody>
</table>
</div>
</div>
</form>
Hope this helps you.
I have this code
<tbody>
<form action="dsf.php" method="post">
<?PHP if(mysql_num_rows($leerdb) > 0) {while ($rs = mysql_fetch_row($leerdb)) {?>
<tr>
<td><input name="idecod[]" type="checkbox" value="<?php echo $rs[0]; ?>" /></td>
<td><?php echo $rs[0]; ?></td>
<td><?php echo $rs[1]; ?></td>
<td><?php echo $rs[2]; ?></td>
<td><?php echo $rs[3]; ?></td>
<td><?php echo $rs[4]; ?></td>
<td><?php echo $rs[5]; ?></td>
<td>BsF. <?php echo $rs[6]; ?></td>
</tr>
<?PHP }}?>
<input class="enviar" type="submit" name="enviar" id="enviar" value="Editar Asesor" />
</form>
</tbody>
I do not know why the submit button doesnt work. When I click on it, nothing happend.
It seems that something in the php loop is making the mess.. But as I know, PHP goes first than HTML, so, when FORM HTML comes, PHP code was already executed.
Where is my error.??
Thanks in advance.
Roberto
You are generating invalid HTML.
You can't have a form wrapped around table rows without wrapping it around the entire table.
You can't have a submit button placed between table rows.
The browser you are using is likely trying to recover from the error in such a way that the form is moved somewhere where it is allowed, but where it doesn't contain any of the controls.
NB: Different browsers recover from having forms in inappropriate parts of tables in different ways.
Use a validator, and write real HTML.
instead of opening the brackets for the while and if, use the php short tags. Example:
<?php if (condition): ?>
output your html here
<?php endif; ?>
Same thing goes for while. read about it here: www.php.net/manual/en/control-structures.while.php
--Edited for clarity.
Database:
tblModule, contains a list of modules that can be enabled or disabled.
tblData, contains a list of trusts and the modules they have enabled. This links to tblModule on tblData.M01 = tblModule.mod_key
The PHP page is accessed from an index page and passes a variable lstModTrust to this page, to limit the returned records from tblData for a single trust. tblData.trust_key
A query runs, qryModuleList which returns a list of all modules. This is used to generate a table of all available modules. Each row shows module name tblModules.mod_name, module code tblModules.mod_code and a checkbox.
qryModData will return a list of the modules that are enabled for a single trust, and the corresponding checkboxes need to be ticked in the table.
This page will then be used to enable and disable modules for a trust. If a module is unticked the entry will be deleted from tblData, if it is ticked an entry will be inserted, and if no change then no change in the DB.
At the moment I'm having trouble getting the checkboxes ticked correctly based on qryModData
Any thoughts anyone?
--Edited to include code--
<table width="50%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td>Module</td>
<td>Module Code</td>
<td> </td>
</tr>
<?php do { ?>
<tr>
<td><?php echo $row_qryModuleList['mod_name']; ?></td>
<td><?php echo $row_qryModuleList['mod_code']; ?></td>
<td><input <?php if (!(strcmp($row_qryModData['M01'],$row_qryModuleList['mod_code']))) {echo "checked=\"checked\"";} ?>name="chkMod" type="checkbox" id="chkMod" value="<?php echo $row_qryModData['M01']; ?>" /></td>
</tr>
<?php } while ($row_qryModuleList = mysql_fetch_assoc($qryModuleList)); ?>
</table>
Then there's two SQL queries, one that generates the list to build the table, and the second which I'm trying to use to set the boxes to ticked.
qryModuleList
SELECT *
FROM tblmodules
ORDER BY mod_name ASC
qryModData
SELECT *
FROM tbldata
WHERE trust_key = varTrust
varTrust is pulled from a URL variable.
Apologies for not including the code in the first place.
--Edit for new code.
<?php while ($row_qryModuleList = mysql_fetch_assoc($qryModuleList)) { ?>
<tr>
<td><?php echo $row_qryModuleList['mod_name']; ?></td>
<td><?php echo $row_qryModuleList['mod_code']; ?></td>
<td><input <?php if (strcmp($row_qryModData['M01'],$row_qryModuleList['mod_key']) != 0) {echo "checked=\"checked\"";} ?>name="chkMod" type="checkbox" id="chkMod" value="<?php echo $row_qryModData['M01']; ?>" /></td>
</tr>
<?php } ; ?>
--Edited for new Code.
<tr class="tblHead">
<td>Module</td>
<td>Module Code</td>
<td>Enabled\Disabled</td>
</tr>
<?php
$mod_data = array();
while ($row_qryModData = mysql_fetch_assoc($qryModData))
array_push($mod_data, $row_qryModData['M01']);
$currentRow = 0;
while ($row_qryModuleList = mysql_fetch_assoc($qryModuleList)) {
?>
<tr bgcolor="<?php echo($currentRow++ % 2)?"#CCFFFF":"#FFCCFF";?>">
<td><?php echo $row_qryModuleList['mod_name']; ?></td>
<td><?php echo $row_qryModuleList['mod_code']; ?></td>
<td><input <?php if (false !== (array_search($mod_data, $row_qryModuleList['mod_key']))) echo "checked=\"checked\""; ?> name="chkMod" type="checkbox" id="chkMod" value="<?php echo $row_qryModData['M01']; ?>" /></td>
</tr>
<?php } ; ?>
I think I'm understanding this now. What you need to do is place all of the allowed modules into an array and use the array_search() function to find it.
Example:
$mod_data = array();
while ($row_qryModData = mysql_fetch_assoc($qryModData)) array_push($mod_data, $row_qryModData['M01']);
That will get all the available modules into one array.
Next, while you cycle through the 'ModuleList' query, use the array_search() method to try and find the 'ModKey' variable in it. If you do, check the box. If not, do nothing.
Example:
<td><input <? if (false !== (array_search($mod_data, $row_qryModuleList['mod_code'])) echo "checked=\"checked\" "; ?>name="chkMod" type="checkbox" id="chkMod" value="<?php echo $row_qryModData['M01']; ?>" /></td>
(The reason I use a "!==" is because the function can return false or something that might equal false and might not. Read the page I've linked above for more)
