astuce très pratique ici. Lorsque vous sélectionnez le type comme « caché » dans la balise d'entrée, la balise d'entrée sera masquée et ne sera pas affichée sur la page, mais l'entrée. La balise sera masquée sur la page. Dans le formulaire, il y a des valeurs de nom et des valeurs de valeur, qui seront également transmises avec le bouton de soumission. Cette balise masquée peut transmettre certains contenus que vous ne souhaitez pas afficher. 2. GET value La valeur GET est transmise en suivant l'url Lorsque la page saute, elle saute avec l'url. Couramment utilisé dans l'utilisation des balises <a> Par exemple : <p class="toolbar" style="margin:0px;padding:0px;border:none;float:none;line-height:1.1em;vertical-align:baseline;font-family:Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace;font-size:10px;color:rgb(255,255,255);background-color:rgb(108,226,108);">? <table border="0" style="margin:0px;padding:0px;font-family:Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace;border:0px;float:none;line-height:1.1em;vertical-align:baseline;font-size:1em;"><tbody style="padding:0px;margin:0px;float:none;line-height:1.1em;vertical-align:baseline;font-size:1em;"><tr style="border-top:0px;padding:0px;margin:0px;float:none;line-height:1.1em;vertical-align:baseline;font-size:1em;" class="firstRow"> <td class="gutter" style="border-width:0px;font-size:1em;color:rgb(175,175,175);line-height:1.1em;padding:0px;margin:0px;float:none;vertical-align:baseline;font-family:Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace;"><p class="line number1 index0 alt2" style="margin:0px;padding:0px .5em 0px 1em;border-width:0px 3px 0px 0px;border-right-style:solid;border-right-color:rgb(108,226,108);float:none;line-height:1.1em;text-align:right;vertical-align:baseline;font-size:1em;white-space:pre;">1</td> <td class="code" style="border-width:0px;font-size:1em;line-height:1.1em;padding:0px;margin:0px;float:none;vertical-align:baseline;font-family:Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace;"> <code class="html plain" style="font-family:Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace;font-size:1em;line-height:1.1em;padding:0px;margin:0px;border:0px;float:none;vertical-align:baseline;"><</code><code class="html keyword" style="color:rgb(0,102,153);padding:0px;font-size:1em;margin:0px;font-family:Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace;line-height:1.1em;border:0px;float:none;vertical-align:baseline;font-weight:bold;">a</code> <code class="html color1" style="font-family:Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace;font-size:1em;line-height:1.1em;padding:0px;margin:0px;border:0px;float:none;vertical-align:baseline;">href</code><code class="html plain" style="font-family:Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace;font-size:1em;line-height:1.1em;padding:0px;margin:0px;border:0px;float:none;vertical-align:baseline;">=</code><code class="html string" style="font-family:Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace;font-size:1em;line-height:1.1em;color:rgb(0,0,255);padding:0px;margin:0px;border:0px;float:none;vertical-align:baseline;">'delete.php?id=value'</code><code class="html plain" style="font-family:Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace;font-size:1em;line-height:1.1em;padding:0px;margin:0px;border:0px;float:none;vertical-align:baseline;">>点我跳转</</code><code class="html keyword" style="color:rgb(0,102,153);padding:0px;font-size:1em;margin:0px;font-family:Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace;line-height:1.1em;border:0px;float:none;vertical-align:baseline;font-weight:bold;">a</code><code class="html plain" style="font-family:Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace;font-size:1em;line-height:1.1em;padding:0px;margin:0px;border:0px;float:none;vertical-align:baseline;">></code> </td> </tr></tbody></table> Après avoir accédé à xxx.php, vous pouvez obtenir la valeur transmise via $_GET['id']. La méthode GET est souvent utilisée dans les URL pour supprimer ou lire un fichier php avec un certain identifiant. 3. SESSION transmettant la valeur SESSION est un type de variable globale, qui est souvent utilisé pour enregistrer des données courantes telles que l'ID utilisateur après la connexion de l'utilisateur. Une fois enregistrées dans SESSION, d'autres pages peuvent être obtenues via SESSION. Pour utiliser SESSION, vous devez ouvrir la session : <p class="toolbar" style="margin:0px;padding:0px;border:none;float:none;line-height:1.1em;vertical-align:baseline;font-family:Consolas, 'Bitstream
