PHP - Editing/updating Data (php & Mysql)
Hello folks,
I can not seem to find out why this code is not being executed properly. Basically, I'd like to edit Records, so I am using forms to retrieve data, make modifications then save them. Code: [Select] <?php //connection to db $results = mysql_query("SELECT * FROM crud WHERE id=".$_GET[id]."") or die (mysql_error()); $row = mysql_fetch_assoc($results); echo "<form action=\"\" method=\"POST\">"; echo "Year: <input type=\"text\" value=".$row['car_year']." name=\"car_year\" /> <br />"; echo "Make: <input type=\"text\" value=".$row['car_make']." name=\"car_make\" /> <br />"; echo "Model: <input type=\"text\" value=".$row['car_model']." name=\"car_model\" /><br /><br />"; echo "Description:<br /><textarea rows=\"15\" cols=\"60\" name=\"description\" />". $row['description']. "</textarea>"; echo "<br /><input type=\"submit\" value=\"save\">"; echo "</form>"; if ($_POST['save']) { $car_year = $_POST['car_year']; $car_make = $_POST['car_make']; $car_model = $_POST['car_model']; $description = $_POST['description']; // Update data $update = mysql_query("UPDATE crud SET car_year='$car_year', car_make='$car_make' car_model='$car_model', description='$description' WHERE id=".$_GET['id']."") or die (mysql_error()); echo 'Update successfull'; } ?> Please HELP!!!! Similar TutorialsHello Im quite confused at what filtering I should use on my data when pulling it from a MySQL database. I don't sanitize my data on input because I am using prepared statements with PHP's PDO Driver which means I don't need to use mysql_real_escape_string() at all. When I pull the data to be displayed i.e. in a HTML Table I use the below function to make it safe for HTML output. public static function htmlSafe($data) { return nl2br(htmlentities($data, ENT_QUOTES)); } However the rules change when Im using a HTML Form to edit the data, and I am unsure what I need to strip out. I.e. What would I need to do to make all data safe to insert into the following form input. <input id = "someInput" type = "text" value = "<?php echo $someVarThatNeedsFiltering ?>" /> Also, one more question, in my html attributes (Valid ones like class, name, id, style, _target) I use a mixture of double quotes(") and single quotes ('), for quoting my values. Which one should I use or which one is more valid, doubles, or singles? I used to be good at this but I changed servers and everything is different... Heres my code so far: Code: [Select] <?php $rated=$_REQUEST['rated']; echo $rated; $rating=$_REQUEST['rating']; echo $rating; // Make a MySQL Connection mysql_connect("localhost", "********", "********") or die(mysql_error()); mysql_select_db("*********") or die(mysql_error()); $result = mysql_query("SELECT * FROM main WHERE username = '$rated'") or die(mysql_error()); $row = mysql_fetch_array( $result ); $votes = $db_field['$rating']; $newvotes = $votes + 1; echo $newvotes; mysql_query("UPDATE main SET $rating = '$newvotes' WHERE username = '$rated'"); ?> Whats going on here is the colomb that I want to update comes as a variable $rated (That works) and then the database selects the row to update with $username (That works) and gets the variable $newvotes by taking the original value of the data its about to update and add 1 to it (That works) Then it updates the field to $newvotes.... I don't know why the update won't go through... there are no errors.... Hi all I have 3 tables Table_1, Table_2 and Table_3 Table_1 is a list of countries, with name and country_id Table_2 is a table that has 3 fields, id, name and description Table 3 is a table that has name, Table_2_id So what I need to do: Display the name and description field of Table_2 in a form Loop through the countries table and display each as an input box and display on the same form When I fill out the form details, the name/description must be inserted into Table_2, creating an id The input boxes data then also needs inserting into Table_3, with the foreign key of Table_2_id So a small example would be: Name: testing Description: this is a test Country of Australia: Hello Country of Zimbabwe: Welcome This means that in Table_2, I will have the following: ============================= | id | name | description | 1 | testing | this is a test ============================= Table_3 ============================= | Table_2_id | name | country_id | 1 | Hello | 20 | 1 | Welcome | 17 ============================= 20 is the country_id of Australia 17 is the country_id of Zimbabwe Code: Generating the input fields dynamically: $site_id = $this->settings['site_id']; $options = ''; $country_code = ''; $query = $DB->query("SELECT country_code, country_id, IF(country_code = '".$country_code."', '', '') AS sel FROM Table_1 WHERE site_id='".$this->settings['site_id']."' ORDER BY country_name ASC"); foreach ($query->result as $row) { $options .= '<label>' . 'Test for ' . $this->settings['countries'][$row['country_code']] . '</label>' . '<br />'; //$row['country_id'] is the country_id from Table_1 $options .= '<input style="width: 100%; height: 5%;" id="country_data" type="text" name="' . $row['country_id'] . '" value="GET_VALUE_FROM_DB" />' . '<br /><br />'; } echo $options; This outputs: Code: [Select] Textareas go here...... <label>Test for Australia</label> <input type="text" value="" name="20" id="country_data" style="width: 100%; height: 5%;"> <label>Test for Zimbabwe</label> <input type="text" value="" name="17" id="country_data" style="width: 100%; height: 5%;"> Now, I need to insert the value of the input field and it's country_id (20 or 17) into Table_3 and also Table_2_id. This then means I could get the value from Table_3 to populate 'GET_VALUE_FROM_DB' But I'm at a loss on how I'd do this. Could someone help me with this? Thanks

I have a MySQL database with a table of products. I use this table to generate a mutliselect form element that is used int a larger form. The larger form contains other information relevant to an issue that we are having with that product (such as an outage). Anyway, the form works fine and the form validation works fine and I write it to the database fine. The issue I'm having is how to save the mutliselect options most efficiently. This is my current process: 1. User creates a new entry from the form and clicks save 2. The form is validated 3. All entries are written to the database in a table called "incidents" (content inclues, timestamps, description of the problem, the impact, who to contact, etc) 4. Because the products list can vary from 1 product to all (~30) products I broke it out into a separate table called "impacted_products". I then loop through each of the selected products and write one row for each product using the id from the row in the "incidents" table to define the tables relationship. Example of DB results: "incidents" +-----------------+------+----------+---------------------+---------+---------+ | notification_id | what | impact | time_start | summary | contact | +-----------------+------+----------+---------------------+---------+---------+ | 235235 | Test | None.... | 2011-02-08 13:41:00 | Test | 3 | +-----------------+------+----------+---------------------+---------+---------+ "impacted_products" +-----+-----------------+------------+---------------------+---------+ | id | notification_id | product_id | timestamp | deleted | +-----+-----------------+------------+---------------------+---------+ | 202 | 235235 | 7 | 2011-02-10 14:30:42 | 0 | | 203 | 235235 | 37 | 2011-02-10 14:30:42 | 0 | | 204 | 235235 | 23 | 2011-02-10 14:30:42 | 0 | +-----+-----------------+------------+---------------------+---------+ 5. Now the users wants to go back and make some updates. 6. They click the edit button from the menu on screen and the form is brought back up and all options/fields are filled out from that which is stored in the database. 7. They make their edits and save again. 8. Now this time it simple updates the "incidents" table but for the products table I do a: "UPDATE impacted_products SET deleted=1 WHERE notification_id='$ID'" and "delete" all the old impacted_products for this particular incident and then loop through all the products that the user still had selected and write them to the database again. 9. And repeat So as you can see this could end up with a lot of "useless" entries in the database since my scripts only pay attention to those "impacted_products" whose deleted value is set to 0. Example: +-----+-----------------+------------+---------------------+---------+ | id | notification_id | product_id | timestamp | deleted | +-----+-----------------+------------+---------------------+---------+ | 176 | 235235 | 37 | 2011-02-08 15:26:25 | 1 | | 177 | 235235 | 43 | 2011-02-08 15:26:25 | 1 | | 178 | 235235 | 37 | 2011-02-08 15:37:58 | 1 | | 179 | 235235 | 43 | 2011-02-08 15:37:58 | 1 | | 180 | 235235 | 1 | 2011-02-08 15:39:49 | 1 | | 181 | 235235 | 7 | 2011-02-08 15:39:49 | 1 | | 182 | 235235 | 37 | 2011-02-08 15:39:49 | 1 | | 183 | 235235 | 43 | 2011-02-08 15:39:49 | 1 | | 184 | 235235 | 1 | 2011-02-08 15:40:53 | 1 | | 185 | 235235 | 7 | 2011-02-08 15:40:53 | 1 | | 186 | 235235 | 37 | 2011-02-08 15:40:53 | 1 | | 187 | 235235 | 43 | 2011-02-08 15:40:53 | 1 | | 188 | 235235 | 37 | 2011-02-10 10:00:47 | 1 | | 189 | 235235 | 1 | 2011-02-10 12:17:05 | 1 | | 190 | 235235 | 7 | 2011-02-10 12:17:05 | 1 | | 191 | 235235 | 13 | 2011-02-10 12:17:05 | 1 | | 192 | 235235 | 37 | 2011-02-10 12:17:05 | 1 | | 193 | 235235 | 23 | 2011-02-10 12:17:05 | 1 | | 194 | 235235 | 1 | 2011-02-10 12:21:52 | 1 | | 195 | 235235 | 7 | 2011-02-10 12:21:52 | 1 | | 196 | 235235 | 13 | 2011-02-10 12:21:52 | 1 | | 197 | 235235 | 37 | 2011-02-10 12:21:52 | 1 | | 198 | 235235 | 23 | 2011-02-10 12:21:52 | 1 | | 199 | 235235 | 7 | 2011-02-10 12:22:26 | 1 | | 200 | 235235 | 37 | 2011-02-10 12:22:26 | 1 | | 201 | 235235 | 23 | 2011-02-10 12:22:26 | 1 | | 202 | 235235 | 7 | 2011-02-10 14:30:42 | 0 | | 203 | 235235 | 37 | 2011-02-10 14:30:42 | 0 | | 204 | 235235 | 23 | 2011-02-10 14:30:42 | 0 | +-----+-----------------+------------+---------------------+---------+ I did it this way beacuase it seems the easiest and fastest way. Otherwise I would have to lookup all the impacted_products from the table that match that notification_id and check 1) Was there a new product selected? If so, add it. 2) Was a product that was selected no longer selected? If so, delete it. 3) Was a product that was selected before still selected now? If so, leave it alone. This seemed like a lot of extra looping and a lot of extra DB queries to essentially end up at the same place. However, I feel that there has still got to be a more efficient way of doing this where I won't have all the extra entries in the impacted_products table. Any ideas? Thanks in advance! Ok, so I'm not quite sure how to explain this, but here it goes: I have table A that contains stats for all players in the NHL, and then I have table B with just a few players. These few players in table B are also in table A, but table B has more information on them. I want to take the stats for these players out of table A and put into table B, and I want table B to update along with table A every time those numbers change. How would I do this? Hi, I want to loop out data from DB in <input> and change and update several posts at the same time. Can you give me a short example, how <input> and maybe foreach could look like? Thanks I am working on a php project in which players can equipt items from there inventory and it shows them there current stats. When players have decided to equipt an item they hit the submit button and the new stats should show. The issue I have is that the data is delaying in update such as: we have 10 strength we equipt a sword with +2 to strength and click submit it displays we have 10 strength we equipt a axe with +3 to strength and click submit it displays 12 strength we equipt a sword with +2 to strength and click submit it displays 13 strength we equipt a sword with +2 to strength and click submit it displays 12 strength .... my code is represented below <?php updateEquiptment(); require("playerInfo.php"); ?> <p title="This stat increases how hard you hit with weapons!">Strength:<?php echo $baseStrength + getModStrength() ?> </p> the functions updateEquiptment and getModStrength are in the playerInfo.php file and are shown like this: $user = $_SESSION['username']; $result = mysql_fetch_row(mysql_query("SELECT equiptment FROM warUsers WHERE name = '$user'")); $equiptment = explode(",",$result[0]); function updateEquiptment() { global $user; $result = mysql_fetch_row(mysql_query("SELECT equiptment FROM warUsers WHERE name = '$user'")) or die(mysql_error()); global $equiptment; $equiptment = explode(",",$result[0]); } //get there modified stats function getModStrength() { $total = 0; global $equiptment; foreach ($equiptment as $value) //loop through every item in the equiptment { if($value == 0 || $value == null) //if nothing is equipt go to the next loop continue; $result = mysql_query("SELECT * FROM items WHERE id = '$value'"); $item = mysql_fetch_row($result); $total += $item[4]; //get the items strength and add it to the total } return $total; } any help on the matter would be greatly appreciated Hey guys, I got another one that i could use some help on. I have a input form that utilizes a javascript that adds additional rows to my table. here is a look at what i got. Code: [Select] <script type="text/javascript"> function insertRow() { var x = document.getElementById('results_table').insertRow(-1); var a = x.insertCell(0); var b = x.insertCell(1); var c = x.insertCell(2); var d = x.insertCell(3); var e = x.insertCell(4); a.innerHTML="<input type=\"text\" name=\"id\">"; b.innerHTML="<input type=\"text\" name=\"place\">"; c.innerHTML="<input type=\"text\" name=\"username\">"; d.innerHTML="<input type=\"text\" name=\"earnings\">"; e.innerHTML="<input type=\"button\" value=\"delete\" onClick=\"deleteRow(this)\">"; } function deleteRow(r) { var i=r.parentNode.parentNode.rowIndex; document.getElementById('results_table').deleteRow(i); } </script> this is my code stored in the header of my page. basically just a button to add a new row and a button in each row to delete rows if needed. here is a look at my html table, pretty basic... Code: [Select] <table id="results_table"> <th>Event ID</th><th>Place</th><th>Username</th><th>Earnings</th> <tr> <td><input type="text" name="id"></td><td><input type="text" name="place"></td><td><input type="text" name="username"></td><td><input type="text" name="earnings"></td><td><input type="button" value="delete" onClick="deleteRow(this)"</td> </tr> </table> Now what I am hoping to acheive is once i submit all of these rows to the database i will insert each of these rows into their own row in the database. is this doable? the structure of my database is: ResultID (Primary Key) Place Earnings UserID (Foreign Key) EventID (Foreign Key) now i think the biggest problem i'm having with submitting data to the database is that in the original HTML form I am typing in the actual username and not the userID. so when it comes to processing I need to do a switch of these two things before I run my query. Should something like this work? Code: [Select] $username = $_POST['username']; $userID = "SELECT userID FROM users WHERE username="$username"; $query = mysql_query($userID); also i've never tried to submit multiple entries at a time. maybe i have to create an array somehow in order to capture each rows data. any thoughts? as always thanks for the help. Hello all, I have form that has several fields. Each field will be saved to a table (which is a relations table we will call markups). The form is built from another table which is an array of categories. The output will build a form with each category and allow the end-user to input data for each category. The information the user will be entering is markup values. Cat1 | Markup Input Cat2 | Markup Input Cat3 | Markup Input I'll be saving the data in their own columns and not as an serialized array to the database. I'm currently looping through the arrayed fields and saving the data to the markup relations table. I've read other forums and serializing the data will be to difficult to retrieve for relationship purposes?? Anyway, here's my question: Let's say the user is entering the markups for the first time. They go down the list of categories and add their markups for each and click save. Cool, no problem just do an INSERT INTO. Then, they go into the category setup screen and add a category then go back to the markup screen and now have to update the category markup that was just added. So now I have to do an UPDATE to the current listed markups table (no problem). But now I have to add another row in the same table from that array. Is there a logical way of handling this. I guess I'm looking for some ideas on how to accomplish this task. I hope you guy understand what I'm after here.

For the last 5 weeks I have been trying to get the following code to work but I am still unable to do it. The code does copy the file from my root folder into another (I eventually plan to use external download onto my server). However, it comes up with the following error: "Cannot instantiate non-existent class: xmlreader in" which refers to this: $xmlReader = new XMLReader(); Does anyone have any experience of transferring data from an XML file to a database? I am using PHP 5 so I dont know why this doesn't work. <?php ini_set('display_errors', 1); error_reporting(-1); $host="hostname"; // $username="username"; // $password="password"; // $db_name="db"; // $tbl_name="productfeed"; // // Connect to server and select database. mysql_connect("$host", "$username", "$password")or ("no connection"); mysql_select_db("$db_name")or die("Database Connection Error"); $xmlReader = new XMLReader(); $filename = "datafeed_98057.xml"; $url = "[url=http://www.ukhomefurniture.co.uk/datafeed.xml]http://www.ukhomefurniture.co.uk/datafeed.xml[/url]"; file_put_contents($filename, file_get_contents($url)); $xmlReader->open($filename); while ($xmlReader->read()) { switch ($xmlReader->name) { case'prod': $dom = new DOMDocument(); $domNode = $xmlReader->expand(); $element = $dom->appendChild($domNode); $domString = utf8_encode($dom->saveXML($element)); $product = new SimpleXMLElement($domString); $product_code = $product->prod['id']; $image = $product->awImage; //insert query if(strlen($product) > 0) { $query = mysql_query("REPLACE INTO productfeed (image) VALUES ('$awImage')"); echo $awImage . "has been inserted </br>"; die('yes it works'); error_reporting(E_ALL); if (ini_get('display_errors')) { ini_set('display_errors', 1); } } break; } } ?> MOD EDIT: DB credentials removed. |
