Aaj hum janenge ki Blogger me conditional tags ki madad se widgets gadgets ko hide show kaise kare? Jab hum blogger me template customization karte hai tab bahut sari problems face karni padti hai.
Jaise ki kisi widget/gadget/sidebar/script/ ko specific page pe dikhana hai ya fir form ko sirf contact us page pe hi dikhana hai aur other pages se hide karna hai.
Example 1. Jab visitor hamare about us page pe land karta hai to sidebar show nahi honi chahiye aur jab visitor post/article pe click kare to sidebar wapas se dikhai deni chahiye.
Example 2. Kisi widget jaise ki labels ko mobile devices me se hide aur destop me show karna hai.
Iske liye hum conditional tags ka use karke blogger me asani se kisi specific parts ko hide aur show kar sakte hai.
Waise to isme bahut tarah ki conditions hoti hai par is post me hum hide/show conditional tags ke bare me janenge.
Conditional tags ko blogger html template me apply kiya jata hai aur yeh kuch is tarah opening <b:if cond….. and closing </b:if> tag hote hai.
Conditional tag example:
<b:if cond='your condition'>YAHAN AAP KA HTML CODE</b:if>

Conditional tags use karne ke fayde
Agar isi ko css code apply na karke conditional tag ka use kare to iske html codes browser me load hi nahi honge jisse site ki speed increase hogi.
Conditional tags kaise use kare?
<b:widget id='ContactForm2' locked='false' title='Agar koi sawal, sujhav hai to is contact form ko fill karke send kare!' type='ContactForm' version='1' visible='true'> <b:includable id='main'> <b:if cond='data:blog.url!=data:blog.homepageUrl'> <b:if cond='data:title != ""'> <h2 class='title'><data:title/></h2> </b:if> <div class='contact-form-widget'> <div class='form'> <form name='contact-form'> <p/> <data:contactFormNameMsg/> <br/> <input class='contact-form-name' expr:id='data:widget.instanceId + "_contact-form-name"' name='name' size='30' type='text' value=''/> <p/> <data:contactFormEmailMsg/> <span style='font-weight: bolder;'>*</span> <br/> <input class='contact-form-email' expr:id='data:widget.instanceId + "_contact-form-email"' name='email' size='30' type='text' value=''/> <p/> <data:contactFormMessageMsg/> <span style='font-weight: bolder;'>*</span> <br/> <textarea class='contact-form-email-message' cols='25' expr:id='data:widget.instanceId + "_contact-form-email-message"' name='email-message' rows='5'/> <p/> <input class='contact-form-button contact-form-button-submit' expr:id='data:widget.instanceId + "_contact-form-submit"' expr:value='data:contactFormSendMsg' type='button'/> <p/> <div style='text-align: center; max-width: 222px; width: 100%'> <p class='contact-form-error-message' expr:id='data:widget.instanceId + "_contact-form-error-message"'/> <p class='contact-form-success-message' expr:id='data:widget.instanceId + "_contact-form-success-message"'/> </div> </form> </div> </div> </b:if></b:includable> </b:widget>
Aap dekh sakte hai is code me maine red txts ko highlight kiya hai jo ki conditional tag hai.
Step 4. Conditional tag successfully apply karne ke bad template ko save karde aur site load karke results dekhe.
Aapko ise apne widget me <b:includable id=’main’> ke bad conditional tag lagana hai aur </b:includable> se pahle </b:if> lagana hai, ab apka widget is condition ko follow karega.
Conditional tags comparison operator pe behave karte hai jaise ki ==(is equal to) aur !=(is not equal to)
Isme (==) ki jagah (!=) lagane pe yeh reverse ho jata hai, matlab ki (==) se widget show hoga (!=) se widget hide hoga.
Niche kuch conditional tags hai jise aap jarurat ke anusar copy karke apne blog me use kar sakte hai.
To show conditional tags
<b:if cond='data:blog.isMobileRequest == "true"'> YAHAN AAP KA HTML CODE </b:if>
<b:if cond='data:blog.isMobileRequest == "false"'> YAHAN AAP KA HTML CODE </b:if>
<b:if cond='data:blog.pageType == "index"'> YAHAN AAP KA HTML CODE </b:if>
<b:if cond='data:blog.pageType == "item"'> YAHAN AAP KA HTML CODE </b:if>
<b:if cond='data:blog.pageType == "static_page"'> YAHAN AAP KA HTML CODE </b:if>
<b:if cond='data:blog.url == "URL of the page"'> YAHAN AAP KA HTML CODE </b:if>
<b:if cond='data:blog.pageType == "error_page"'> YAHAN AAP KA HTML CODE </b:if>
Blogger widget ko post aur static page pe show karne ke liye:
<b:if cond='data:blog.url == data:post.url'> YAHAN AAP KA HTML CODE </b:if>
<b:if cond='data:blog.pageType == "archive"'> YAHAN AAP KA HTML CODE </b:if>
<b:if cond='data:blog.url == data:blog.homepageUrl'> YAHAN AAP KA HTML CODE </b:if>
Jaise ki maine pahle btaya tha ki agar aap in conditional tags me == ki jagah != replace karke widgets ko hide karne me use kar sakte hai.
Example
Widget show karne ke liye:
<b:if cond='data:blog.url == data:blog.homepageUrl'> YAHAN AAP KA HTML CODE </b:if>
<b:if cond='data:blog.url != data:blog.homepageUrl'> YAHAN AAP KA HTML CODE </b:if>
Ye conditional tag aapke blog ka design, speed, SEO improve karne me helpful sabit honge jisse aapke blog ka look professional lagega jo ki ek successful blogger ki pahchan hai.
