  1. 2 problems with my code, the filter_var doesn't seem to work at all for any of my variables, also the spam_scrubber function doesn't seem to clean \r, and \n, when put in my contact form, it cleans all the rest though just fine. <?php // resources.php function spam_scrubber($value){ $very_bad = array('to:', 'cc:', 'bcc:', 'content-type:', 'mime-version:', 'multipart-mixed:', 'content-transfer-encoding:'); foreach ($very_bad as $v){ if (stripos($value, $v) !== false) return ''; } $value = str_replace(array( "\r", "\n", "%0a", "%0d"), ' ', $value); return trim($value); }//end of spam_scrubber function $scrubbed = array_map('spam_scrubber', $_POST); $comments = strip_tags($scrubbed['comments']); $url = $scrubbed['url']; if (isset($url)){ filter_var($url, FILTER_VALIDATE_URL, FILTER_SANITIZE_URL); } else { echo NULL; } $url2 = $scrubbed['url2']; if (isset($url2)){ filter_var($url2, FILTER_VALIDATE_URL, FILTER_SANITIZE_URL); } else { echo NULL; } $linkpageurl = $scrubbed['linkpageurl']; if (isset($linkpageurl)){ filter_var($linkpageurl, FILTER_VALIDATE_URL, FILTER_SANITIZE_URL); } else { echo NULL; } $linkpageurl2 = $scrubbed['linkpageurl2']; if (isset($linkpageurl2)){ filter_var($linkpageurl2, FILTER_VALIDATE_URL, FILTER_SANITIZE_URL); } else { echo NULL; } $email = $scrubbed['email']; if (isset($email)){ filter_var($email, FILTER_VALIDATE_EMAIL, FILTER_SANITIZE_EMAIL); } else { echo NULL; } $pagerank = $scrubbed['pagerank']; if (isset($pagerank)){ filter_var($pagerank, FILTER_VALIDATE_INT, FILTER_SANITIZE_NUMBER_INT); } else { echo NULL; } if (!empty($email) && !empty($url) && !empty($linkpageurl) && !empty($comments) && !empty($pagerank)){ $body = "Email: {$email}\n\n Url: {$url}\n\n Url2: {$url2}\n\n Pagerank: {$pagerank}\n\n Linkpageurl: {$linkpageurl} \n\n Linkpageurl2: {$linkpageurl2}\n\n Comments: {$comments}"; $body = wordwrap($body, 70); $headers = "From: {$email}\r\n"; mail('email@example.com', 'Link Exchange Form Submission', $body, $headers); echo '<p><em>Thank you for contacting us.</em></p><div id="formecho"><h3>Form submission received, we will get back to you soon.</h3></div>'; $_POST = array(); } else { echo '<p style="font-weight: bold; color: #C00">Please fill out the form completely.</p>'; } ?> <div id="form"> <form action="linkexchangecontactform2.php" method="post"> <p><b>Email:</b> <input type="text" size="30" maxlength="50" name="email" value="<?php if(isset($scrubbed['submit']))echo $scrubbed['email']; ?>" /></p> <p><b>Url:</b> <input type="text" size="30" maxlength="50" name="url" value="<?php if(isset($scrubbed['url']))echo $scrubbed['url']; ?>" /></p> <p><b>2nd Url (leave empty if you have just 1 website):</b><br /> <input type="text" size="30" maxlength="50" name="url2" value="<?php if(isset($scrubbed['url2']))echo $scrubbed['url2']; ?>" /></p> <p><b>Pagerank:</b> <input type="text" size="5" maxlength="10" name="pagerank" value="<?php if(isset($scrubbed['pagerank']))echo $scrubbed['pagerank']; ?>" /></p> <p><b>Link page url:</b> <input type="text" size="30" maxlength="50" name="linkpageurl" value="<?php if(isset($scrubbed['linkpageurl']))echo $scrubbed['linkpageurl']; ?>" /></p> <p><b>2nd Link page url (leave empty if you have just 1 website):</b><br /> <input type="text" size="30" maxlength="50" name="linkpageurl2" value="<?php if(isset($scrubbed['linkpageurl2']))echo $scrubbed['linkpageurl2']; ?>" /></p> <p><b>Comments:</b><br> <textarea name="comments" rows="7" cols="40"><?php if (isset($scrubbed['comments'])) echo $scrubbed['comments']; ?></textarea></p> <p><input type="submit" name="submit" value="Submit" /></p> </form></div>
  2. My brain must be dead, because while I read the book, I am having trouble devising a solution to this problem. I would like to include a button on a page of query results that allows users to filter the results to those that match only certain criteria. I realize that it's not a good idea to run a whole new query just for this filtering, so I have been trying to look for a solution, but to no avail. Any tips? I'm sorry for being vague, I'd just rather not give away too much about the site's structure. Thank you!
  3. Here are some questions that crossed my mind while reading Chapter 5 (Version 0.5) Page 86 The book states, "If you also set a requiredValue attribute for the item in question, your error message can indicate what the required value is via {value}." My question: Larry, could you please provide an example showing how the value of {value} would be set? Page 91 Please show the code I would need to "create user-related scenarios for changing passwords". Also, in which circumstances would I set a scenario on an existing instance, as opposed to creating a new user? Page 93 Why is it necessary to write "filter" twice in this code: 'filter', 'filter'=>'strip_tags' ? Page 94 Wouldn't declaring search terms as safe be a security risk? Here is the code from the book: array('id, user_id, live, title, content, date_updated, date_published', 'safe', 'on'=>'search'), Page 95 Why would we need to compare passwords if the user is only just registering? How would he/she already know a password? Quoting from the book: // Password must match the comparison: array('pass', 'compare', 'compareAttribute'=>'passCompare', 'on'=>'register'), Page 95 I have read a credible article on the Internet stating that ENUM fields are "evil". If I prefer to avoid using an ENUM field, and instead use a separate table of "types" which lists these values 'public','author','admin' etc, and the table has a one to many relationship with User.type, how would I obtain the values from the types table for use in this rule? Here is the code from the book: array('type', 'in', 'range'=>array('public','author','admin')), Page 97 The book states: "Also, when you have a model that’s not based upon a database, you’ll need to add the attribute names and values to the attributeLabels() method yourself." How do these attribute labels end up being incorporated into various HTML forms? Page 101 Quoting from the book: $this->user_id = Yii::app()->user->id; My question: I understand the relationship, but aren't there many user.id values to choose from? How does the framework know which id is the correct one? Page 102 Here's a syntax question: 'date_entered' in the first example becomes $this->created in the second example. How can these refer to the same table field? Page 102 Can you please provide an example how I could "return false in the event handler method"? Quoting from the book: "As a final note on this concept, if the event that’s about to take place shouldn’t occur–for example, the model should not be saved for some reason, just return false in the event handler method." Thanks.
  4. Hi everybody. I have used the following code from http://www.yiiframework.com/wiki/361/simple-way-to-use-autocomplete-using-different-id-and-display-value/ . My table name is dog and I'm interested in three attributes: id, name and size. So far I have gotten an autocomplete field working which is populated with the name-attribute values as typed in by the end user. The following code does that: Under extensions: <?php Yii::import("zii.widgets.jui.CJuiAutoComplete"); class myAutoComplete extends CJuiAutoComplete { /** * Run this widget. * This method registers necessary javascript and renders the needed HTML code. */ public function run() { list($name,$id)=$this->resolveNameID(); // Get ID Attribute of actual hidden field containing selected value $attr_id = get_class($this->model).'_'.$this->attribute; if(isset($this->htmlOptions['id'])) $id=$this->htmlOptions['id']; else $this->htmlOptions['id']=$id; if(isset($this->htmlOptions['name'])) $name=$this->htmlOptions['name']; if($this->hasModel()) { echo CHtml::textField($name,$this->value,$this->htmlOptions); echo CHtml::activeHiddenField($this->model, $this->attribute); }else { echo CHtml::textField($name,$this->value,$this->htmlOptions); CHtml::hiddenField($name,$this->value,$this->htmlOptions); } if($this->sourceUrl!==null) $this->options['source']=CHtml::normalizeUrl($this->sourceUrl); else $this->options['source']=$this->source; // Modify Focus Event to show label in text field instead of value if (!isset($this->options['focus'])) { $this->options['focus'] = 'js:function(event, ui) { $("#'.$id.'").val(ui.item.label); return false; }'; } if (!isset($this->options['select'])) { $this->options['select'] = 'js:function(event, ui) { $("#'.$id.'").val(ui.item.label); $("#'.$attr_id.'").val(ui.item.id); }'; } $options=CJavascript::encode($this->options); //$options = $this->options; $js = "jQuery('#{$id}').autocomplete($options);"; $cs = Yii::app()->getClientScript(); $cs->registerScript(__CLASS__.'#'.$id, $js); } } Under models: public static function usersAutoComplete($name='') { $sql= 'SELECT id ,name AS label FROM dog WHERE name LIKE :name'; $name = $name.'%'; return Yii::app()->db->createCommand($sql)->queryAll(true,array(':name'=>$name)); } Under Controllers: public function actionUsersAutocomplete() { $term = trim($_GET['term']) ; if($term !='') { $users = Users::usersAutoComplete($term); echo CJSON::encode($users); Yii::app()->end(); } } And finally under views: $this->widget('ext.myAutoComplete', array( 'model'=>$model, 'attribute'=>'user_id', 'name'=>'user_autocomplete', 'source'=>$this->createUrl('dog/usersAutoComplete'), 'options'=>array( 'minLength'=>'0', ), 'htmlOptions'=>array( 'style'=>'height:20px;', ), )); What I Want to achieve still is have a dropdown list with sizes (small, medium or large) which would be added to my SQL statement. I.e. if the dropdownlist is set to large then something like "....WHERE size='large'...." should be included in the SQL query. Im really not sure how to achieve this. If no records are found then I need to display a "Sorry, no results" message in the autocomplete list and finally if a record is found and selected by the user a button needs to be included to do a database search based upon the 'id' found in the above code. Thank you very much for your help!
