PHP - "" Blank Field?
I'm confused...
how do you say check if the field in MYSQL is blank? it's not getting what I'm attempting to get. Please help. I want to do actionA... if either of these 3 conditions are true tf1=="RED" tf1=="" tf2=="" AND tf=="apple" if(tf1=="RED" or tf1=="" or tf2=="" AND tf=="apple") { do actionA... } Similar TutorialsCan someone please help me with an array problem i can not figure out. I need the array to be numbered from 1 to how ever many fields that are needed in the form and have a mysql field name and the title of the field also in the array. 1, "mysql_field_name", "Title of form field" 2, "", "" and so on then the form will be shown based on the array. I have the following draft code which I am working with. any suggestions on how i may do this array ? Code: [Select] <?php $options = array( '1'=> array('fieldtext'=>'option1', 'mysqlfield'=>'option1'), '2'=> array('fieldtext'=>'option2', 'mysqlfield'=>'option2'), '3'=> array('fieldtext'=>'option3', 'mysqlfield'=>'option3'), '4'=> array('fieldtext'=>'option4', 'mysqlfield'=>'option4'), ); // $options = array(1 => "option1", "option2", "option3", "option4"); // the line above works but i want to include the name of the mysql field as well. $userid = 1; ?> <div style="align: center; margin: 12px; font-family:Tahoma;"> <br><br><?php if ($_POST['Update'] != "Update") { // check if form submitted yet, if not get data from mysql. $res = db_query("SELECT * FROM `users` WHERE `userid` = '" . $userid . "'"); foreach($options as $key => $value) { $_POST[$key] = mysql_result($res, 0, $value); } $ok_to_update = "no"; } elseif ($_POST['Update'] == "Update") { // check if form submitted yet, if so get POST data. // error checking // foreach($options as $key => $value) { // $_POST[$i] = ""; // } $ok_to_update = "yes"; } if ($_POST['Update'] == "Update" && $ok_to_update == "yes") { // $res = db_query("INSERT INTO `users` () VALUES ()"); // add user details to database. ?><p><br><br><br>Thank you for updating</p><?php } else { ?><form name="form1" method="post" action=""> <?php foreach($options as $key => $value) { ?><p><?php echo($value); ?>: <input type="text" name="<?php echo($key); ?>" value="<?php echo($_POST[$key]);?>"></p> <?php } ?> <input name="Update" type="submit" value="Update"> </form> <?php } ?> </div> Hi, bit stuck on how to find and replace "<" and ">" with "<" and ">". I basically have a database record that outputs to screen and I need the code in the <code> tags to be rendered to the screen. I therefore need it to go through the whole array variable from the db and change the symbols just inside the code tags. Please be aware that the code tags might happen more than once here's an example below Code: [Select] <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1> </code> <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1> </code> the desired output would be: <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1 </code> <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1 </code> help on this would be great Cheers Rob ...added to an error log?

Hi guys I'm struggling a bit, I need to replace a word that occurs multiple times in text with an array("up","down","forward","backwards") of words. $find = "left"; $replace = array("up","down","forward","backwards"); $text = "left left left left"; echo str_replace($find,$replace,$text); The Output is: array array array array Did try this with a foreach statement as well, but no luck. Is there a better way of doing this?

I want to reset the content of a particular field in all rows of a table to a specific value, I was thinking of nesting a query inside a query for the same table, but was not sure that this would work: ... $query = "SELECT * FROM music WHERE picked >'0'"; $result = mysql_query($query) or die ("Couldn't execute query."); /* reset the picked field to zero (0) */ while ($row = mysql_fetch_array($result)) { $picked = 0; $query= "UPDATE music SET picked='$picked' WHERE title='$title'"; $selectresult = mysql_query($query) or die ("Problem with the query: $query<br>" . mysql_error()); } ... Is this the correct approach or is there a better way of doing this? I am getting the following error when using composer: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"? Just started. I am pretty sure composer.json wasn't changed. journalctl doesn't show anything. Maybe Doctrine related, however, nothing seems to help.
Any ideas?

As you can see below, I just tried adding the new "required" field the same way as the other 4 were set up, but it is not working (I think I have to do something different because the new "required field" is a "radio" type and the rest are "text"). The relevant parts of the code are below. Any assistance would be appreciated Code: [Select] <script type="text/JavaScript"> function verify() { var Skill = document.indiv_reg.skill.value; var Fname = document.indiv_reg.name.value; var Hphn = document.indiv_reg.home_num.value; var Email = document.indiv_reg.email.value; var Tname = document.indiv_reg.tname.value; if ((Fname =="") || (Skill =="") || (Hphn =="") || (Email =="") || (Tname =="")) { alert('Please Fill Out ALL Required Fields'); } else { document.indiv_reg.submit(); } } </script> <?php $url = "https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=6Y76L7TX6FVRW"; $sport = $_GET['sport']; $league = $_GET['league']; $visitor = $_GET['name']; $skill = $_GET['skill']; $tname = $_GET['tname']; $tcap = $_GET['tcap']; $homephn = $_GET['home_num']; $cellphn = $_GET['cell_num']; <?php * Denotes a Required Field<br /> <br /> <form name="indiv_reg" method="GET" action="tourney_mailRedirect.php"> Sport:<br /> <input type="text" name="sport" value="'.$sport.'" readonly="readonly" /><br /> <br /> Tournament:<br /> <input type="text" size="90" name="league" value="'.$league.'" readonly="readonly" /><br /> <br /> * Please select preferred skill level:<br /> <input type="radio" name="skill" value="recreational" /> Recreational<br /> <input type="radio" name="skill" value="competitive" /> Competitive<br /> <br /> * Name:<br /> <input type="text" name="name" /><br /> <br /> * Team Name:<br /> <input type="text" name="tname" /><br /> <br /> Team Captain:<br /> <input type="text" name="tcap" /><br /> <br /> * Home Phone:<br /> <input type="text" name="home_num" /><br /> <br /> Cell Phone:<br /> <input type="text" name="cell_num" /><br /> <br /> * Email:<br /> <input type="text" name="email" /><br /> <br /> ?> I have a form where people will be putting in specific info such as their names and other info.

Thanks for your assistance Steve This topic has been moved to PHP Installation & Configuration. http://www.phpfreaks.com/forums/index.php?topic=347922.0 Hi, I currently have an if, elseif, else program that starts off with Code: [Select] if( $v_name == "" || $v_msg == "" ) echo "something" how do I turn this into a switch? but the very next elseif I have Code: [Select] elseif( strcspn( $_REQUEST['msg'], '0123456789' ) == strlen( $_REQUEST['msg'] ) ) echo "something" is it possible to turn this into a switch with 2 different strings like that to evaluate? I have a registration form on my website and after Registration I want the user to activate first his account. I don't have problem on sending this email to the user. What I want to appear is like this.. GoodDay "username", Blah Blah! how can you actually do that? I know that you can do that through session variables but the thing is email's can't accept scripts on sending emails. how can I get the value from a session variable for example and convert it to plain html text so that i can OUTPUT it to the email.. HELP PLEASE! hello, I was wondering what is the point of writing for a dropdown: <?php if ($_POST[inputfieldID] == "value") { echo "selected"; } ?> or for a checkbox/ radio button: <?php if ($_POST['cb/radioID'] == "value") { echo "checked"; } ?> I guess it's for after submit, if there is any error, the values filled will still be echoed in the inputfield, or am i wrong? But then if that is true, i have a php search box where i use AJAX object to to send all the input they filled in after submit. But after pushing submit the inputted values remain. I guess when using AJAX to send the information i don't need <?php if ($_POST[inputfieldID] == "value") { echo "selected"; } ?> in my html forms? Little confused Can maybe somebody bring clearness Hi all, Using a form with check boxes divided into different categories, I collect data selected by the user. I now want to combine each choice in each category with each choice in the other categories and list the combinations to the user. If the user chooses one or more options in each category, it is relatively easy to nest foreach loops, since the number of categories will always be the same. For example, if the form contains three categories of options, the code will be: Code: [Select] foreach ($form['cat_1'] as $k1 => $val1) { foreach ($form['cat_2'] as $k2 => $val2) { foreach ($form['cat_3'] as $k3 => $val3) { echo $val1.' _ '.$val2.' _ '.$val3.'<br/>'; } } } Things get complicated if the user does not select options within a given category. More generally, I want to be able to generate the list regardless of the number of categories in which the user selects options. Thank you in advance for your advice. Hey guys! I have the following doubt: I have a php file that does the following alongside with other code not displayed he $fp = fopen("emails.txt", "w"); It opens a txt file called emails.txt that is in the same folder where the php is saved but how do I tell $fp = fopen("/folderbefore/emails.txt", "w"); ?? In other words, how do I write the path on the script that the emails.txt is located in a previous folder where the php file is located?? Thanks in advance for your help Cheers! |
